Summary

The Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) plugin for WordPress is affected in all versions up to and including 3.4.5. Missing file extension, MIME type and size validation in the signature field's upload handling, combined with no guards against PHP execution in the upload directory, lets users upload files that may be executable (CWE-434). An unauthenticated remote attacker can upload such files, which may lead to remote code execution.

Description from the CNA

The Extensions For CF7 (Contact form 7 Database, Conditional Fields and Redirection) plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.4.5 via the extcf7_submit function. This is due to missing file extension, MIME type, and size validation in the signature field's validation_filter(), combined with the absence of PHP-execution guards in the upload directory and a sanitize_file_name() bypass that converts shell.php- into shell.php. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
