The Cybersecurity and Infrastructure Security Agency (CISA) has added multiple actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog. These include flaws affecting Zyxel firewalls, Cisco's Adaptive Security Appliance (ASA), CyberPanel, North Grid, and ProjectSend. The addition of these vulnerabilities highlights the ongoing threat landscape and the urgent need for organizations to implement timely patching and robust vulnerability management practices. A particularly concerning vulnerability is CVE-2024-51378, a critical flaw in CyberPanel with a CVSS score of 10.0, allowing attackers to bypass authentication and execute arbitrary commands, leading to ransomware deployment and data theft. Other vulnerabilities, such as the decade-old Cisco ASA flaw (CVE-2014-2120), despite its lower severity score, are also being actively exploited, emphasizing the importance of addressing even older vulnerabilities.
CISA's urgent warning focuses on the immediate need for remediation. Federal agencies face a December 25th, 2024 deadline to patch affected systems, underlining the severity of the threat. The vulnerabilities affect various systems, ranging from firewalls to open-source software, indicating a broad attack surface. The agency strongly advises organizations to implement mitigations, including patching, access restriction, and vigilant monitoring for suspicious activity. Failure to address these vulnerabilities leaves organizations vulnerable to unauthorized access, data breaches, ransomware attacks, and significant operational disruptions.
