Description

OpenX is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to adequately validate user- supplied input.

An attacker can exploit this vulnerability to upload arbitrary code and execute it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.

The issue affects OpenX 2.8.1 and prior.
