Request a Quote Form Plugin <= 2.5.5 — Unauthenticated Code Injection via 'path' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Request a Quote – Quote Forms for Any WordPress Site.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 2.5.6, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Request a Quote – Quote Forms for Any WordPress Site to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Mitchell.

The Request a Quote plugin for WordPress is vulnerable to Code Injection in versions up to, and including, 2.5.5 via the emd_delete_file AJAX action. This is due to the emd_delete_file() handler deriving a PHP function name from the attacker-controlled $_POST['path'] parameter and invoking it dynamically via the variable-function call $sess_name(), and the handler being registered for wp_ajax_nopriv with its only protection being a nonce that the plugin prints into the public quote-form page via wp_localize_script. This makes it possible for unauthenticated attackers to invoke arbitrary zero-argument PHP functions on the server, such as phpinfo(), potentially exposing sensitive server configuration and credentials, or executing other destructive built-in PHP functions.
