Description
The RapiSafe – Secure Multi File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handleAjaxRemoveUpload function in all versions up to, and including, 1.0.4. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The nonce required to invoke the removal handler is exposed in public-facing JavaScript as RSMFCF7Vars.nonce on every Contact Form 7 page rendering a RapiSafe upload field, making it obtainable by any unauthenticated visitor.
