Description
AVideo through 29.0 contains an OS command injection vulnerability in plugin/API/standAlone/functions.php where the listFFmpegProcesses() function interpolates unsanitized keyword parameters inside single quotes without escaping. Attackers who can craft a valid encrypted codeToExec payload can break out of the single-quoted grep context and execute arbitrary OS commands as the web-server user.
