Description

This module exploits a PHP Object Injection vulnerability in SugarCRM CE
which could be abused to allow unauthenticated users to execute arbitrary PHP code with
the permissions of the webserver. The dangerous unserialize() call exists in the
'/service/core/REST/SugarRestSerialize.php' script. The exploit abuses the __destruct()
method from the SugarCacheFile class to write arbitrary PHP code into the /custom directory.
