CVE-2020-27868

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Qognify Ocularis 5.9.0.395. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of serialized objects provided to the EventCoordinator endpoint. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-11257.
