CISA alerts about critical ManageEngine RCE vulnerability

The Cybersecurity and Infrastructure Security Agency (CISA) now includes a Java deserialization vulnerability of critical severity that affects numerous Zoho ManageEngine products. In servers running unpatched Zoho ManageEngine PAM360 and Password Manager Pro (without authentication) or Access Manager Plus (with authentication) software, this security flaw (CVE-2022-35405) can be exploited in low-complexity attacks to gain remote code execution without requiring user interaction. According to ManageEngine, they have removed the vulnerable components from PAM360, Access Manager Plus, and Password Manager Pro. Patches were released in June, and administrators are requested to upgrade to a fixed version, as a proof-of-concept exploit is already public.

THREAT ADVISORY - DOOMSDAY CRITICAL LINUX BUG

Description A severe vulnerability, CVE-2024-47176, has been discovered in the Common UNIX Printing System (CUPS). It was made public on September 26, 2024, and affects Linux systems with cups-browsed enabled. This vulnerability requires the victim to start a print job, and if your cups-browsed is enabled, it could make him vulnerable to attacks that could lead to their computer being commandeered over the network or internet. Impact Attackers can exploit this vulnerability to hijack devices on networks, potentially gaining control over systems. While successful exploitation requires user interaction (the initiation of a print job), the risks remain significant, especially for systems that expose CUPS to public networks. Affected Versions CUPS is bundled with various Linux distributions, and the vulnerability affects: Most Linux distributions with CUPS and cups-browsed enabled Some BSD systems Potentially Google ChromeOS, Oracle's Solaris, and other distributions Remediation To mitigate the risk associated with this vulnerability, it is recommended to: Disable or remove the cups-browsed service to prevent exposure. Block access to UDP port 631 on firewalls to limit external access. Update CUPS when security patches become available. Consider removing CUPS entirely if it is not needed for printing tasks.

Manufacturing Sector Vulnerable to RCE Flaw

Description PTC, a leading software provider for critical manufacturing organizations, has recently addressed an RCE flaw tracked as CVE-2024-6071. The vulnerability, rated CVSS 10, exists in the PTC Creo Elements/Direct license server. It enables unauthorized remote command execution and lateral movement within critical manufacturing and industrial organizations, including Volvo, Lufthansa, Medtronic, HP, Merck, and GE. Impact The flaw impacted the license server of Creo Elements/Direct, a direct modeling CAD software used for creating 3D designs. Although PTC claims the flaw has not been exploited, its severity prompted immediate patching. Exploitation requires network access, as the license server is typically not exposed to the internet. Affected Versions Thomas Riedmaier discovered a vulnerability in the Creo Elements/Direct license server: Versions 20.7.0.0 and earlier Remediation Apply PTC's patch for Creo Elements/Direct. Confirm that the license server is not exposed to the internet. Limit access to authorized personnel. Isolate license servers from critical systems. Monitor logs for unusual activities. Perform vulnerability scans and penetration tests. Include CVE-2024-6071 in the incident response plan. Stay updated with PTC for new patches or information. Verify security standards meet industry standards and regulations.

Remote Code Execution Vulnerability CVE-2024-6387 in glibc-based Linux Systems

Description The Qualys Threat Research Unit issued an advisory for CVE-2024-6387 on July 1 regarding a vulnerability affecting glibc-based Linux systems that allow unauthenticated remote code execution known as “regreSSHion.” It is a regression of CVE-2006-5051, reintroduced with OpenSSH version 8.5p1. While exploitation is challenging, it can have severe impacts. Lab tests show it requires about 10,000 attempts over 6-8 hours against 32-bit hosts, with 64-bit hosts theoretically at risk but not publicly proven. Impact This vulnerability may allow attackers to escalate privileges fully if a client fails to authenticate within 120 seconds (600 seconds for legacy OpenSSH versions). Exploiting the regeSSHion vulnerability could enable attackers to: ● Fully compromise a susceptible host ● Exfiltrate sensitive data ● Propagate laterally within the network to internal hosts ● Encrypt and hold critical data for ransom Affected Versions ● OpenSSH versions before 4.4p1 ● OpenSSH versions between 8.5p1 and 9.7p1 Previous patches for CVE-2006-5051 and CVE-2008-4109 have resolved the flaw. OpenBSD systems are unaffected. OpenSSH versions in Red Hat Enterprise Linux 6, 7, and 8 are not vulnerable, as the regression was introduced in OpenSSH 8.5p1, which postdates these versions. Remediation To deal with this menace, ensure timely upgrades of OpenSSH upon patch availability. Set LoginGraceTime to 0, acknowledging the potential risk of denial of service if simultaneous connections exceed MaxStartups. Restrict SSH access to internet-exposed hosts and implement network segmentation to curtail lateral movement effectively.

Snowflake Customers Hit With ‘Significant’ Data Theft In Attacks: Mandiant

Description Mandiant researchers have identified a recent breach of the Snowflake Cloud Data Platform by the Uncategorized Threat Actor Group (UNC5537) that could potentially expose approximately 165 organizations. The data theft, which occurred in mid-April 2024, appears to have exploited Snowflake's stolen customer credentials obtained through infostealer malware campaigns on non-Snowflake systems. Impact The absence of multi-factor authentication (MFA) on the affected accounts facilitated the breach. Notable organizations affected include Ticketmaster, Santander Bank, and Advance Auto Parts. Over 100 customers were confirmed as impacted. Remediation ● Add an extra layer of security by enabling MFA for all accounts. ● Strengthen Password Policies by implementing long, complex passwords and changing them regularly. ● Regularly audit and monitor accounts for suspicious activity. ● Enforce secure configurations and keep systems updated with patches. ● Conduct frequent security assessments and penetration testing.

CVE-2024-23897: Check Critical Jenkins Arbitrary File Leak Vulnerability Now!

On 24 January 2024, the Jenkins team issued a security advisory disclosing a critical vulnerability that affects the Jenkins CI/CD tool. Jenkins is a Java-based open-source automation server run by over 1 million users that helps developers build, test and deploy applications, enabling continuous integration and continuous delivery. The critical vulnerability is tracked as CVE-2024-23897 and affects Jenkins 2.441 and earlier. LTS 2.426.2 and earlier does not disable a feature of its CLI command parser that replaces the ‘@’ character followed by a file path in an argument with the file’s contents, allowing unauthenticated attackers to read arbitrary files on the Jenkins controller file system that can lead to RCE. According to security researchers from ShadowServer, there are approximately 45,000 unpatched Jenkins instances, most of which are in China (12,000) and the United States (11,830). Two Proof of Concepts (PoCs) exploits have been released to the public and could be leveraged by attackers to compromise unpatched Jenkins servers. According to the Cyber Security Agency (CSA) of Singapore, as of 30 January 2024, the vulnerability is reportedly being actively exploited. Who Is Affected? Anyone who is running Jenkins 2.441 and earlier is affected by this vulnerability. How Can I Fix It? Jenkins users are urged to upgrade to Jenkins 2.442 and LTS 2.426.3. How Can NodeZero Help? All NodeZero™️ users can run an autonomous pentest to determine if their systems are vulnerable to the Jenkins vulnerability. We also recommend running a follow-on pentest to verify that any remediation steps taken, such as patching, are effective.
