Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions AVideo versions prior to 29.0

Description An incomplete fix in the execAsync() function allows command substitution using backticks or the $() syntax. This occurs because escaped commands are re-wrapped in double-quoted sh -c calls. An attacker can exploit this to inject arbitrary operating system commands through the on publish.php endpoint of the Live plugin, bypassing the protection provided by escapeshellarg(), which is a function used to sanitize strings for use in shell commands.

Recommendations Update to version 29.0 or later. As a temporary mitigation, restrict access to the on publish.php endpoint of the Live plugin.
