Description
WordPress Plugin CM Download Manager is prone to a vulnerability that lets remote attackers inject and execute arbitrary code because the application fails to sanitize user-supplied input. Attackers can exploit this issue to execute arbitrary code within the context of the affected webserver process; this may result in total compromise of the web server. WordPress Plugin CM Download Manager version 2.0.3 is vulnerable; prior versions may also be affected.
