CVE-2024-24216 is a critical remote code execution (RCE) vulnerability identified in Zentao versions 18.0 through 18.10. Zentao is a project management software commonly used for agile development and issue tracking. The vulnerability resides in the checkConnection method within the /app/zentao/module/repo/model.php file. This flaw is classified under CWE-77, which relates to improper neutralization of special elements used in a command ('Command Injection'). The vulnerability allows an unauthenticated attacker to execute arbitrary commands on the underlying server remotely without any user interaction. The CVSS 3.1 base score of 9.8 reflects the high severity, indicating that the exploit is network accessible (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the ease of exploitation and the critical impact make this a significant threat. The absence of vendor or product details in the provided data suggests that the vulnerability is specific to the Zentao software itself, and the affected versions are clearly identified. The vulnerability likely stems from insufficient input validation or sanitization in the checkConnection method, allowing attackers to inject and execute system-level commands remotely, potentially leading to full system compromise.

For European organizations using Zentao versions 18.0 to 18.10, this vulnerability poses a severe risk. Successful exploitation could lead to complete system compromise, allowing attackers to steal sensitive project data, intellectual property, or credentials. It could also enable attackers to pivot within the network, disrupt project management workflows, or deploy ransomware or other malware. Given the critical nature of project management tools in coordinating software development and business operations, disruption or data loss could have cascading effects on productivity and operational continuity. Additionally, organizations subject to GDPR and other data protection regulations could face significant compliance and reputational consequences if sensitive data is exposed or systems are compromised. The lack of authentication requirement and user interaction means that attackers can exploit this vulnerability remotely and automatically, increasing the risk of widespread attacks if the vulnerability is not promptly addressed.

European organizations should immediately identify and inventory all instances of Zentao software in use, specifically versions 18.0 through 18.10. Since no official patch links are provided, organizations should monitor Zentao vendor communications for security updates or patches addressing CVE-2024-24216. In the interim, organizations should restrict network access to the Zentao application, limiting it to trusted internal networks or VPN users only. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the checkConnection method can provide temporary protection. Conduct thorough input validation and sanitization on any user inputs related to repository connections if custom modifications exist. Regularly review application and system logs for unusual command execution attempts or anomalies. Additionally, organizations should prepare incident response plans to quickly contain and remediate any exploitation attempts. Finally, consider upgrading to a newer, unaffected version of Zentao once a patch is available or evaluate alternative project management solutions if immediate patching is not feasible.
