Vulnerability description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in the "DesignManager" module in the "action.admin_bulk_css.php" and "action.admin_bulk_template.php" files. A remote authenticated attacker with Designer permission can reach an unserialize call with a crafted value in the "m1_allparms" parameter and execute arbitrary code on the target system.
