Description
This module exploits a PHP unserialize() in Pimcore before 5.7.1 to execute arbitrary code. An authenticated user with "classes" permission could exploit the vulnerability.
The vulnerability exists in the "ClassController.php" class, where the "bulk-commit" method makes it possible to exploit the unserialize function when passing untrusted values in "data" parameter.
Tested on Pimcore 5.4.0-5.4.4, 5.5.1-5.5.4, 5.6.0-5.6.6 with the Symfony unserialize payload.
Tested on Pimcore 4.0.0-4.6.5 with the Zend unserialize payload.
