CVE-2020-10504Public exploitNetwork attack vector

Comment tampering via missing CSRF validation

Published Mar 12, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Chadha PHPKB Standard Multi-Language 9 allows remote attackers to edit comments through a crafted request. The admin/edit-comment.php handler accepts a credentialed POST containing a comment ID and replacement name, email, text, and status without validating a CSRF token. Exploitation requires a logged-in Superuser to load attacker-controlled content, after which the browser submits the edit with the user's session and can alter the selected comment.
