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.
