CVE-2024-46213 is a remote code execution (RCE) vulnerability identified in REDAXO CMS version 2.11.0. REDAXO CMS is an open-source content management system widely used for website management, particularly in German-speaking regions. The vulnerability allows an attacker to execute arbitrary code remotely over the network (AV:N), with low attack complexity (AC:L), but requires the attacker to have high privileges (PR:H) on the system. No user interaction (UI:N) is needed, and the vulnerability affects the confidentiality, integrity, and availability of the system (C:H/I:H/A:H). The vulnerability is unscoped (S:U), meaning the impact is limited to the vulnerable component. Although the exact technical vector details and affected versions beyond 2.11.0 are not specified, the presence of RCE means an attacker could potentially take full control of the CMS server, execute malicious payloads, manipulate data, or disrupt services. The vulnerability was reserved in September 2024 and published in October 2024, with no known exploits reported yet. The lack of patch links suggests that a fix may not be publicly available at the time of reporting, emphasizing the need for vigilance and mitigation.

The impact of CVE-2024-46213 is significant for organizations using REDAXO CMS 2.11.0. Successful exploitation could lead to complete system compromise, allowing attackers to execute arbitrary commands, access sensitive data, modify website content, or disrupt services. This could result in data breaches, defacement, loss of customer trust, and operational downtime. Given the CMS's role in managing web content, attackers might also use compromised systems as a foothold for lateral movement within networks or to launch further attacks. Organizations in sectors relying on web presence and content management, such as media, education, government, and e-commerce, are particularly at risk. The requirement for high privileges to exploit the vulnerability somewhat limits the attack surface but does not eliminate risk, especially if privilege escalation vulnerabilities exist or insider threats are present.

Organizations should immediately audit their REDAXO CMS installations to identify if version 2.11.0 is in use. Until a patch is released, restrict access to the CMS administration interface to trusted IP addresses and enforce strong authentication mechanisms, including multi-factor authentication for privileged users. Monitor logs for unusual activities indicative of attempted exploitation. Employ network segmentation to isolate CMS servers from critical infrastructure. Regularly back up website data and configurations to enable recovery in case of compromise. Stay informed via official REDAXO channels for security updates and apply patches promptly once available. Additionally, conduct a thorough review of user privileges to ensure the principle of least privilege is enforced, minimizing the number of users with high-level access.
