Description
WordPress Plugin Default Thumbnail Plus is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly verify user-supplied input. An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. WordPress Plugin Default Thumbnail Plus version 1.0.2.3 is vulnerable; prior versions may also be affected.
