AVideo through 29.0 contains an OS command injection vulnerability in the ffmpeg.json.php endpoint where notifyCode and callback parameters are concatenated into a shell command without escaping. Attackers who can craft a valid encrypted payload can inject arbitrary shell metacharacters into these fields to execute OS commands as the web-server user.
