Spug through 3.4.0 contains a remote code execution vulnerability in the ping_check function that interpolates user-supplied monitor addresses directly into shell commands without validation. Authenticated users with monitor permissions can inject shell metacharacters via the /monitor/run_test/ endpoint to execute arbitrary commands as the Spug process user.
