Description
The ARMember plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 4.0.27 via the 'X-FILENAME' HTTP header. This makes it possible for unauthenticated attackers to upload and overwrite certain files (e.g., CSS) to directories outside the 'wp-content/uploads/armember' directory.
