HIGH 7.8MITIGATE

CVE-2024-39835 is a high-severity flaw (CVSS 7.8) affecting robot operating system. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A code injection vulnerability has been identified in the Robot Operating System (ROS) 'roslaunch' command-line tool, affecting ROS distributions Noetic Ninjemys and earlier. The vulnerability arises from the use of the eval() method to process user-supplied, unsanitized parameter values within the substitution args mechanism, which roslaunch evaluates before launching a node. This flaw allows attackers to craft and execute arbitrary Python code.
