Technical details

An authorization weakness in the enterprise synchronization endpoint permitted low-privileged authenticated users to register unauthorized managed servers. Insufficiently protected synchronization responses could then execute attacker-controlled SQL statements on the Central server database. This network-based attack requires valid credentials but no additional user interaction; successful exploitation grants Enterprise Administrator privileges and arbitrary code execution with service-level privileges.
