NIS2: What you need to know

NIS2 Umsetzung gezielt auf den Weg bringen!

The deadline for the implementation of NIS2 is approaching – by October 17, 2024, stricter cybersecurity measures are to be transposed into law in Germany via the NIS2 Implementation Act. Other member states will develop their own legislature based on EU Directive 2022/2555. We have taken a close look at this directive for you to provide you with the most important pointers and signposts for the entry into force of NIS2 in this short video. In this video, you will find out whether your company is affected, what measures you should definitely take, which cybersecurity topics you need to pay particular attention to, who you can consult in this regard and what the consequences of non-compliance are.

Learn about the Cyber Resilience Act, which provides a solid framework to strengthen your organization’s resilience against cyberattacks. The ENISA Common Criteria will help you assess the security of your IT products and systems and take a risk-minimizing approach right from the development stage. Also prioritize the introduction of an information management system, for example by implementing ISO 27001 certification for your company. Seek advice about IT baseline protection from specialists recommended by the BSI or your local responsible office.

In addition to the BSI as a point of contact for matters relating to NIS2, we are happy to assist you and offer certified solutions in the areas of vulnerability management and penetration testing. By taking a proactive approach, you can identify security gaps in your systems at an early stage and secure them before they can be used for an attack. Our vulnerability management solution automatically scans your system for weaknesses and reports back to you regularly. During penetration testing, a human tester attempts to penetrate your system to give you final assurance about the attack surface of your systems.

You should also make it a habit to stay up to date with regular cybersecurity training and establish a lively exchange with other NIS2 companies. This is the only way for NIS2 to lead to a sustainable increase in the level of cyber security in Europe.

NIS2: From impending doom to effective measures

Winter is coming: The motto of House Stark from the series “Game of Thrones” indicates the approach of an undefined disaster. One could also surmise something similar when reading many articles that are intended to set the mood for the upcoming NIS2 Implementation Act (NIS2UmsuCG). Is NIS2 a roller of ice and fire that will bury the entire European IT landscape and from which only those who attend one of the countless webinars and follow all the advice can save themselves?

NIS2 as such is merely a directive issued by the EU. It is intended to ensure the IT security of operators of important and critical infrastructures, which may not yet be optimal, and to increase cyber resilience. Based on this directive, the member states are now called upon to create a corresponding law that transposes this directive into national law.

What is to be protected?

The NIS Directive was introduced by the EU back in 2016 to protect industries and service providers relevant to society from attacks in the cybersphere. This regulation contains binding requirements for the protection of IT structures in companies that operate as critical infrastructure (KRITIS) operators. These are companies that play an indispensable role within society because they operate in areas such as healthcare services, energy supply and transport. In other words, areas where deliberately caused disruptions or failures can lead to catastrophic situations – raise your hand if your household is equipped to survive a power outage lasting several days with all its consequences…

As digitalisation continues to advance, the EU had to create a follow-up regulation (NIS2), which on the one hand places stricter requirements on information security, but on the other hand also covers a larger group of companies that are “important” or “particularly important” for society. These companies are now required to fulfil certain standards in information security.

Although the NIS2 Directive was already adopted in December 2022, the member states have until 17 October 2024 to pass a corresponding implementing law. Germany will probably not make it by then. Nevertheless, there is no reason to sit back. The NIS2UmsuCG is coming, and with it increased demands on the IT security of many companies and institutions.

Who needs to act now?

Companies from four groups are affected. Firstly, there are the particularly important organisations with 250 or more employees or an annual turnover of 50 million euros and a balance sheet total of 43 million euros or more. A company that fulfils these criteria and is active in one of the following sectors: energy, transport, finance/insurance, health, water/sewage, IT and telecommunications or space is particularly important.

In addition, there are the important organisations with 50 or more employees or a turnover of 10 million euros and a balance sheet total of 10 million euros. If a company fulfils these criteria and is active in one of the following sectors: postal/courier, chemicals, research, manufacturing (medical/diagnostics, IT, electrical, optical, mechanical engineering, automotive/parts, vehicle construction), digital services (marketplaces, search engines, social networks), food (wholesale, production, processing) or waste disposal (waste management), it is considered important.

In addition to particularly important and important facilities, there are also critical facilities, which continue to be defined by the KRITIS methodology. Federal facilities are also regulated.

What needs to be done?

In concrete terms, this means that all affected companies and institutions, regardless of whether they are “particularly important” or “important”, must fulfil a series of requirements and obligations that leave little room for interpretation and must therefore be strictly observed. Action must be taken in the following areas:

Risk management

Affected companies are obliged to introduce comprehensive risk management. In addition to access control, multi-factor authentication and single sign-on (SSO), this also includes training and incident management as well as an ISMS and risk analyses. This also includes vulnerability management and the use of vulnerability and compliance scans.

Reporting obligations

All companies are obliged to report “significant security incidents”: these must be reported to the BSI reporting centre immediately, but within 24 hours at the latest. Further updates must be made within 72 hours and 30 days.

Registration

Companies are obliged to determine for themselves whether they are affected by the NIS2 legislation and to register themselves within a period of three months. Important: Nobody tells a company that it falls under the NIS2 regulation and must register. The responsibility lies solely with the individual companies and their directors.

Evidence

It is not enough to simply take the specified precautions; appropriate evidence must also be provided. Important and particularly important facilities will be inspected by the BSI on a random basis, and appropriate documentation must be submitted. KRITIS facilities will be inspected on a regular basis every three years.

Duty to inform

In future, it will no longer be possible to sweep security incidents under the carpet. The BSI will be authorised to issue instructions to inform customers about security incidents. The BSI will also be authorised to issue instructions on informing the public about security incidents.

Governance

Managing directors are obliged to approve risk management measures. Training on the topic will also become mandatory. Particularly serious: Managing directors are personally liable with their private assets for breaches of duty.

Sanctions

In the past, companies occasionally preferred to accept the vague possibility of a fine rather than making concrete investments in cyber security measures, as the fine seemed quite acceptable. NIS2 now counters this with new offences and in some cases drastically increased fines. This is further exacerbated by the personal liability of managing directors.

As can be seen, the expected NIS2 implementation law is a complex structure that covers many areas and whose requirements can rarely be covered by a single solution.

What measures should be taken as soon as possible?

Continuously scan your IT systems for vulnerabilities. This will uncover, prioritise and document security gaps as quickly as possible. Thanks to regular scans and detailed reports, you create the basis for documenting the development of the security of your IT infrastructure. At the same time, you fulfil your obligation to provide evidence and are well prepared in the event of an audit.

On request, experts can take over the complete operation of vulnerability management in your company. This also includes services such as web application pentesting, which specifically identifies vulnerabilities in web applications. This covers an important area in the NIS2 catalogue of requirements and fulfils the requirements of § 30 (risk management measures).

Conclusion

There is no single, all-encompassing measure that will immediately make you fully NIS2-compliant. Rather, there are a number of different measures that, taken together, provide a good basis. One component of this is vulnerability management with Greenbone. If you keep this in mind and put the right building blocks in place in good time, you will be on the safe side as an IT manager. And winter can come.

Supposedly pro-Russian hackers try to exploit Sharepoint vulnerability

Update from 2023-12-06:

Last week, we reported on pro-Russian hacktivists scanning for vulnerable SharePoint Servers to exploit a critical vulnerability (CVE-2023-29357).

New findings suggest that the group, calling themselves “Zarya”, is undertaking various exploit-attempts, including directory traversal and targeting specific vulnerabilities in systems such as OpenWRT-Routers. The IP address 212.113.106.100, associated with these activities, has been observed in several different exploit attempts. In addition to simple reconnaissance, specific attacks on configuration files and Admin-APIs have been detected. This case re-emphasizes the importance of securing systems against such threats and shows, how unprotected or poorly configured systems can become targets of such attacks.

A critical vulnerability for Sharepoint (CVE-2023-29357), is being targeted by presumably pro-Russian attackers who are trying to exploit this vulnerability.

The Internet Storm Center has discovered corresponding activity on its honeypots. The severity for this vulnerability is critical (a score of 9.8 out of 10), and the attack complexity is very low, making this vulnerability particularly dangerous. Greenbone customers can benefit from the automatic detection of this vulnerability in our Enterprise Feed. Microsoft offers a security update since June 12, 2023, Microsoft customers who missed the update should install it now.

IT security update November 2023: Critical vulnerabilities and threats

In the November 2023 commVT Intelligence Update, several critical vulnerabilities and security threats have come to light. Cisco’s Internetworking Operating System (IOS) XE Software Web User Interface (UI) was found to be vulnerable to two actively exploited critical vulnerabilities, allowing attackers to execute arbitrary code remotely. The curl command-line tool, widely used across various platforms, faced a serious vulnerability that could result in arbitrary code execution during SOCKS5 proxy handshakes. VMware is urging immediate updates for its vCenter Server due to a critical vulnerability potentially leading to remote code execution. Multiple vulnerabilities were found in versions of PHP 8; one is a particularly critical deserialization vulnerability in the PHAR extraction process. Additionally, SolarWinds Access Rights Manager (ARM) was found susceptible to multiple critical vulnerabilities, emphasizing the urgency to update to version 2023.2.1. Lastly, two F5 BIG-IP vulnerabilities were discovered to be actively exploited, with mitigation options available and outlined below.

Cisco IOS XE: Multiple Critical Vulnerabilities

Two actively exploited critical CVSS 10 vulnerabilities were discovered in Cisco’s Internetworking Operating System (IOS) XE Software Web User Interface (UI); CVE-2023-20198 and CVE-2023-20273. Combined, they allow an attacker to remotely execute arbitrary code as the system user and are estimated to have been used to exploit tens of thousands of vulnerable devices within the past few weeks. Greenbone has added detection for both the vulnerable product by version [1], and another aimed at detecting the BadCandy implanted configuration file [2]. Both are VTs included in Greenbone’s Enterprise vulnerability feed.

Cisco IOS was created in the 1980s and used as the embedded OS in the networking technology giant’s routers. Fast forward to 2023, IOS XE is a leading enterprise networking full-stack software solution that powers Cisco platforms for access, distribution, core, wireless, and WAN. IOS XE is Linux-based, and specially optimized for networking and IT infrastructure, routing, switching, network security, and management. Cisco devices are pervasive in global IT infrastructure and used by organizations of all sizes, including large-scale enterprises, government agencies, critical infrastructure, and educational institutions.

Here’s how the two recently disclosed CVEs work:

• CVE-2023-20198 (CVSS 10 Critical): Allows a remote, unauthenticated attacker to create an account [T1136] on an affected system with privilege level 15 (aka privileged EXEC level) access [CWE-269]. Privilege level 15 is the highest level of access to Cisco IOS. The attacker can then use that account to gain control of the affected system.
• CVE-2023-20273 (CVSS 7.2 High): A regular user logged into the IOS XE web UI, can inject commands [CWE-77] that are subsequently executed on the underlying system with the system (root) privileges. This vulnerability is caused by insufficient input validation [CWE-20]. CVE is also associated with a Lua-based web-shell [T1505.003] implant dubbed “BadCandy”. BadCandy consists of an Nginx configuration file named `cisco_service.conf` that establishes a URI path to interact with the web-shell implant but requires the webserver to be restarted.

Cisco has released software updates for mitigating both CVEs in IOS XE software releases, including versions 17.9, 17.6, 17.3, and 16.12 as well as available Software Maintenance Upgrades (SMUs) and IT security teams are strongly advised to urgently install them. Cisco has also released associated indicators of compromise (IoC), Snort rules for detecting active attacks, and a TAC Technical FAQs page. Disabling the web UI prevents exploitation of these vulnerabilities and may be suitable mitigation until affected devices can be upgraded. Publicly released proof of concept (PoC) code [1][2] and a Metasploit module further increase the urgency to apply the available security updates.

Critical Vulnerability In The Curl Tool

A widespread vulnerability has been discovered in the popular curl command line tool, libcurl, and the many software applications that leverage them across a wide number of platforms. Tracked as CVE-2023-38545 (CVSS 9.8 Critical), the flaw makes curl overflow a heap-based buffer [CWE-122]] in the SOCKS5 proxy handshake that can result in arbitrary code execution [T1203]. Greenbone’s community feed includes several NVTs [1] to detect many of the affected software products and will add additional detections for CVE-2023-38545 as more vulnerable products are identified.

CVE-2023-38545 is a client-side vulnerability exploitable when passing a hostname to the SOCKS5 proxy that exceeds the maximum length of 255 bytes. If supplied with an excessively long hostname, curl is supposed to use local name resolution and pass it on to the resolved address only. However, due to the CVE-2023-38545 flaw, curl may actually copy the overly long hostname to the target buffer instead of copying just the resolved address there. The target buffer, being a heap-based buffer, and the hostname coming from the URL results in the heap-based overflow.

While the severity of the vulnerability is considered high because it can be exploited remotely and has a high impact to the confidentiality, integrity, and availability (CIA) of the underlying system, the SOCKS5 proxy method is not the default connection mode and must be declared explicitly. Additionally, for an overflow to happen an attacker also needs to cause a slow enough SOCKS5 handshake to trigger the bug. All versions of curl are affected between v7.69.0 (released March 4th, 2020) until v8.3.0. The vulnerable code was patched in v8.4.0 commit 4a4b63daaa.

VMware vCenter Server: Multiple Vulnerabilities

CVE-2023-34048 is a critical severity vulnerability that could allow a malicious actor with network access to vCenter Server to cause an out-of-bounds write [CWE-787] potentially leading to remote code execution (RCE). The affected software includes VMware vCenter Server versions 6.5, 6.7, 7.0, and 8.0. VMWare has issued a security advisory to address both vulnerabilities which states that there are no known mitigations other than installing the provided updates. Both vulnerabilities can be detected by Greenbone’s enterprise vulnerability feed [1]. The vCenter Server patch also fixes CVE-2023-34056, a medium-severity information disclosure resulting from improper authorization [CWE-285].

Although there are no reports that CVE-2023-34048 is being actively exploited in the wild attackers have proven adept at swiftly converting threat intelligence into exploit code. Research by Palo Alto Networks Unit 42 threat research group shows that on average an exploit is published 37 days after a security patch is released.

Here are some brief details on both CVEs:

• CVE-2023-34048 (CVSS 9.8 Critical): vCenter Server contains an out-of-bounds write [CWE-787] vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger this vulnerability to achieve remote code execution (RCE). The Distributed Computing Environment Remote Procedure Call (DCERPC) protocol facilitates remote procedure calls (RPC) in distributed computing environments, allowing applications to communicate and invoke functions across networked systems.
• CVE-2023-34056 (CVSS 4.3 Medium): vCenter Server contains a partial information disclosure vulnerability. A malicious actor with non-administrative privileges to vCenter Server may leverage this issue to access unauthorized data.

Multiple Vulnerabilities Discovered In PHP 8

Several vulnerabilities were identified in PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3. Although the group of vulnerabilities does include one critical and two high-severity vulnerabilities, these require particular contexts to be present for exploitation; either deserializing PHP applications using PHAR or else using PHP’s core path resolution functions on untrusted input. Greenbone’s enterprise VT feed includes multiple detection tests for these vulnerabilities across multiple platforms.

Here are brief descriptions of the most severe recent PHP 8 vulnerabilities:

• CVE-2023-3824 (CVSS 9.8 Critical): A PHAR file (short for PHP Archive) is a compressed packaging format in PHP, which is used to distribute and deploy complete PHP applications in a single archive file. While reading directory entries during the PHAR archive loading process, insufficient length checking may lead to a stack buffer overflow [CWE-121], potentially leading to memory corruption or remote code execution (RCE).
• CVE-2023-0568 (CVSS 8.1 High): PHP’s core path resolution function allocates a buffer one byte too small. When resolving paths with lengths close to the system `MAXPATHLEN` setting, this may lead to the byte after the allocated buffer being overwritten with NULL value, which might lead to unauthorized data access or modification. PHP’s core path resolution is used for the `realpath()` and `dirname()` functions, when including other files using the `include()`, `include_once()`, `require()`, and `require_once()`, and during the process of resolving PHP’s “magic” constants” such as `__FILE__` and `__DIR__`.
• CVE-2023-0567 (CVSS 6.2 Medium): PHP’s `password_verify()` function may accept some invalid Blowfish hashes as valid. If such an invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid [CWE-287]. Notably, this vulnerability has been assigned different CVSS scores by NIST (CVSS 6.2 Medium) and the PHP group CNA (CVSS 7.7 High), the difference being that the PHP Group CNA considers CVE-2023-0567 a high risk to confidentiality while NIST does not. CNAs are a group of independent vendors, researchers, open source software developers, CERT, hosted service, and bug bounty organizations authorized by the CVE Program to assign CVE IDs and publish CVE records within their own specific scopes of coverage.

SolarWinds Access Rights Manager (ARM): Multiple Critical Vulnerabilities

SolarWinds Access Rights Manager (ARM) prior to version 2023.2.1 is vulnerable to 8 different exploits; one critical and two additional high-severity vulnerabilities (CVE-2023-35182, CVE-2023-35185, and CVE-2023-35187). These include authenticated and unauthenticated privilege escalation [CWE-269], directory traversal [CWE-22], and remote code execution (RCE) at the most privileged “SYSTEM” level. Greebone’s Enterprise vulnerability feed includes both local security check (LSC) [1] and remote HTTP detection [2].

SolarWinds ARM is an enterprise access control software for Windows Active Directory (AD) networks and other resources such as Windows File Servers, Microsoft Exchange services, and Microsoft SharePoint as well as virtualization environments, cloud services, NAS devices, and more. The widespread use of ARM and other SolarWinds software products means that its vulnerabilities have a high potential to impact a wide range of large organizations including critical infrastructure.

These and more recent vulnerabilities are disclosed in SolarWinds’ security advisories. Although no reports of active exploitation have been released, mitigation is highly recommended and available by installing SolarWinds ARM version 2023.2.1.

F5 BIG-IP: Unauthenticated RCE And Authenticated SQL Injection Vulnerabilities

Two RCE vulnerabilities in F5 BIG-IP, CVE-2023-46747 (CVSS 9.8 Critical) and CVE-2023-46748 (CVSS 8.8 High), have been observed by CISA to be actively exploited in the wild soon after PoC code was released for CVE-2023-46747. A Metasploit exploit module has also since been published. F5 BIG-IP is a family of hardware and software IT security products for ensuring that applications are always secure and perform the way they should. The platform is produced by F5 Networks, and it focuses on application services ranging from access and delivery to security. Greenbone has added detection for both CVEs [1][2].

CVE-2023-46747 is a remote authentication bypass [CWE-288] vulnerability while CVE-2023-46748 is a remote SQL injection vulnerability [CWE-89] that can only be exploited by an authenticated user. The affected products include the second minor release (X.1) for major versions 14-17 of BIG-IP Advanced Firewall Manager (AFM) and F5 Networks BIG-IP Application Security Manager (ASM).

If you are running an affected version you can eliminate this vulnerability by installing the vendor-provided HOTFIX updates [1][2]. The term “hotfix” implies that the patch can be applied to a system while it is running and operational, without the need for a shutdown or reboot. If updating is not an option, CVE-2023-46747 can be mitigated by downloading and running a bash script that adds or updates the `requiredSecret` attribute in the Tomcat configuration, which is used for authentication between Apache and Tomcat, and CVE-2023-46748 can be mitigated by restricting access to the Configuration utility to allow only trusted networks or devices, and ensuring only trusted user accounts exist thereby limiting the attack surface.

CVE News: Critical vulnerabilities Atlassian and F5 Big vulnerability tests released by Greenbone

Our developers have provided vulnerability tests for two critical vulnerabilities in widely used enterprise software. Within a very short time, tests for CVE 2023-22518 und CVE 2023-46747 were integrated, and customers of Greenbone’s Enterprise Feed were protected.

Knowledge management tools Confluence and Jira from Australian vendor Atlassian have been hit by a serious security vulnerability, rated 9.8 out of 10 on the CERT scale. Since November 8, CVE 2023-22518 has been actively exploited by attackers gaining unauthorized access to company data, according to media reports.

According to the company, the “authentication flaw” affects all versions of Confluence Data Center and Server, but not the cloud version at Atlassian itself. For anyone else, including users of Jira, but especially all publicly accessible Confluence servers, there is a “high risk and need to take immediate action”, writes Atlassian.

We reacted quickly and provided our customers with appropriate tests before ransomware attacks could be successful. Customers of the Greenbone Enterprise Feed were warned and reminded of the patch via update.

Remote code execution: F5 BIG-IP allows request smuggling

Also at the end of October, security researchers from Praetorian Labs discovered a serious vulnerability (CVE-2023-46747) in the products of application security expert F5. The American company’s solutions are designed to protect large networks and software environments; the software, which was launched in 1997 as a load balancer, is primarily used in large enterprises.

However, according to the experts, attackers can remotely execute code on the BIG-IP servers by adding arbitrary system commands to the administration tools via manipulated URLs. Details can be found at Praetorian; patches are available, and a long list of BIG-IP products of versions 13, 14, 15, 16, and 17 are affected, both in hardware and software.

We reacted quickly and integrated tests into its vulnerability scanners on the same day, which test the BIG-IP installations at Greenbone Enterprise for vulnerable versions and, if necessary, point to the patches listed at F5.

Our vulnerability management products, the Greenbone Enterprise Appliances, offer the best protection.

Professional vulnerability management is an indispensable part of IT security. It enables the early detection of risks and provides valuable instructions for their elimination.
The Greenbone Enterprise Feed is updated daily to detect new vulnerabilities. We therefore recommend that you regularly update and scan all your systems. Please also read this article on IT security and the timeline of common attack vectors.

Current Report on the State of IT Security in Germany 2023

On November 2, Federal Minister of the Interior Nancy Faeser and Claudia Plattner, President of the Federal Office for Information Security (BSI), presented the latest report on the state of IT security in Germany. Attacks with ransomware represent the largest and most frequent risk, but by far not the only one. As long as these attacks cannot be completely prevented, systems must become more secure in order to prevent or at least reduce damage.

In Germany, there are a number of initiatives to improve vulnerability management. These include the National IT Security Act (IT-SiG) and the BSI’s IT-Grundschutz Compendium. The “nationwide situation picture” rightly called for by BSI President Claudia Plattner can thus map the threat situation to the situation of vulnerable systems, thereby helping to warn in advance and respond quickly and effectively in the specific event of an attack.

“Digitization makes many things in our everyday lives easier. At the same time, it creates new areas of attack,” says Federal Minister of the Interior Nancy Faeser. We need to counter the growing risks posed by progressive networking with automated tools and processes. By using them, companies and organizations can better protect their IT systems and reduce the probability of a successful cyber attack.

Insecure systems make it easier for attackers to cause damage. Improving vulnerability management is therefore an important step toward increasing IT security in Germany.Insecure systems make it easier for attackers to wreak havoc. Improving vulnerability management is therefore an important step towards increasing IT security in Germany.
