A code injection vulnerability has been identified in the Robot Operating System (ROS) 'rostopic' command-line tool. This flaw, affecting ROS distributions Noetic Ninjemys and earlier, allows a local user to execute arbitrary code through the --filter option of the 'echo' verb. The vulnerability stems from the direct use of user-provided input within the eval() function without proper sanitization, posing a significant security risk to ROS deployments.
Successful exploitation of CVE-2024-41921 allows an attacker with local access to the system running ROS to execute arbitrary Python code. This could lead to complete system compromise, including data theft, modification, or destruction. Attackers could leverage this to gain persistent access, install malware, or disrupt robotic operations. The impact is particularly severe in environments where ROS controls critical infrastructure or sensitive processes, as malicious code execution could have cascading consequences. The lack of sanitization makes crafting exploits relatively straightforward for attackers familiar with Python.
CVE-2024-41921 is not currently listed on the CISA KEV catalog. The EPSS score is likely to be medium, given the potential for code execution and the relative ease of exploitation once local access is obtained. Public proof-of-concept exploits are anticipated given the vulnerability's nature and the widespread use of ROS. The vulnerability was publicly disclosed on 2025-07-17.

Due to the absence of a patched version, immediate mitigation focuses on limiting exposure and restricting access. The primary recommendation is to restrict access to the 'rostopic' tool to trusted users only. Implement strict access controls to prevent unauthorized individuals from executing commands. Consider using a Web Application Firewall (WAF) or proxy to filter incoming requests and block malicious payloads. Input validation on the --filter option is crucial; however, implementing robust validation within the 'rostopic' tool itself may be challenging. Monitor system logs for suspicious activity related to 'rostopic' and Python execution.
Actualice ROS a una versión posterior a Noetic Ninjemys. Como solución temporal, evite usar la opción '--filter' con entradas no confiables en el comando 'rostopic echo'. Considere deshabilitar o restringir el acceso a la herramienta 'rostopic' en entornos donde la seguridad es crítica.

CVE-2024-41921 is a code injection vulnerability in the ROS 'rostopic' tool affecting Noetic Ninjemys and earlier versions. The --filter option allows arbitrary Python code execution via the eval() function.
If you are using ROS Noetic Ninjemys or an earlier version and have not restricted access to the 'rostopic' tool, you are potentially affected by this vulnerability.
A patched version is not currently available. Mitigation involves restricting access to 'rostopic', implementing input validation, and monitoring system logs.
While no active exploitation has been confirmed, the vulnerability's nature and ease of exploitation suggest that it is likely to be targeted.
