Descriptions

The Bit Form WordPress plugin before 1.9 does not validate the file types uploaded via it's file upload form field, allowing unauthenticated users to upload arbitrary files types such as PHP or HTML files to the server, leading to Remote Code Execution.

The Bit Form plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the saveFormEntry function in versions up to, and including, 1.8.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
