CVE-2025-1949Network attack vector

Browser script execution via unencoded form action

Published Mar 4, 2025 · Updated Mar 4, 2025

Reflected XSS in the URL handler in ZZCMS 2025 allows remote attackers to execute script in a visitor's browser via a crafted URL. The register_nodb.php form action emits the user-controlled $_SERVER['PHP_SELF'] value without output encoding, allowing request-path markup to enter the response. Exploitation requires a visitor to open the crafted URL; executed script can read or alter data available to that visitor's ZZCMS session.
