The vulnerability lies in the 'hz' verb, which reports the publishing rate of a topic and accepts a user-provided Python expression via the --filter option. This input is passed directly to the eval() function without sanitization, allowing a local user to craft and execute arbitrary code.","cvssScore":8.4,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-94","CWE-95"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ros2/ros2cli/pull/1001","tags":[]},{"url":"https://github.com/ros2/ros2cli/pull/133#discussion_r223081766","tags":[]}],"exploitRefs":[{"url":"https://github.com/ros2/ros2cli/pull/1001","tags":[]},{"url":"https://github.com/ros2/ros2cli/pull/133#discussion_r223081766","tags":[]}],"hasPoc":true,"ai":null}
