tag_summary = "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.";

tag_solution = "Reportedly, the vendor fixed this issue in OpenX 2.8.2. Symantec has
not confirmed this information. Please contact the vendor for details.";
