Description
WordPress Plugin N-Media Website Contact Form with File Upload is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to properly sanitize 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 N-Media Website Contact Form with File Upload version 1.3.4 is vulnerable; prior versions may also be affected.
Remediation
