  • →Send a direct unauthenticated HTTP GET request to /includes/mysql2i/mysql2i.func.php; a vulnerable CouchCMS instance will return a PHP fatal error string disclosing the full server path. ↗
  • →Send a direct unauthenticated HTTP GET request to /addons/phpmailer/phpmailer.php; a vulnerable CouchCMS instance will return a PHP fatal error string disclosing the full server path. ↗
  • →Match response body for both 'mysql2i.func.php on line 10' AND 'Fatal error: Cannot redeclare mysql_affected_rows() in' to confirm exploitation of the mysql2i path disclosure vector. ↗
  • →Match response body for both 'phpmailer.php on line 10' AND 'Fatal error: Call to a menber function add_event_listener() on a non-object in' to confirm exploitation of the phpmailer path disclosure vector. ↗
  • ·The vulnerability only triggers if PHP is configured to display errors (display_errors = On); hardened production servers with error display disabled will not return the path disclosure response strings. ↗
  • ·The Nuclei template uses stop-at-first-match, so only one of the two paths needs to return a positive match for the check to succeed; both paths should be tested independently in manual assessments. ↗
