Description

The module doesn't sufficiently escape user-entered values when executing commands on the server allowing an attacker to execute whatever commands are available to the web server user (e.g. www-data).
This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer PDFThumb".
