Description
The vulnerability allows a remote attacker to execute arbitrary commands.
The vulnerability exists due to improper neutralization of special elements used in an os command in sanitizeFFmpegCommand() in plugin/API/standAlone/functions.php when processing a crafted encrypted ffmpeg command that is later executed via sh -c. A remote attacker can send a specially crafted encrypted payload containing $() command substitution to execute arbitrary commands.
Exploitation requires the ability to craft a valid encrypted payload, and legacy installations without saltV2 are at higher risk.
