Wp Contact Form 7 Db Handler
Monthly
Arbitrary file deletion in the WP Contact Form 7 DB Handler WordPress plugin (versions up to and including 3.0) can be achieved by chaining CSRF, UNION-based SQL injection, and PHP object deserialization. A remote unauthenticated attacker who lures a logged-in administrator to a malicious page can delete arbitrary server files, including wp-config.php, which typically forces the site into a re-installation state and enables full site takeover. No public exploit identified at time of analysis, though Wordfence's detailed write-up effectively documents the exploit chain.
