Description

The Career Section plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.7 via the CV upload handler. This is due to missing file type validation. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
