CVE-2025-14837Public exploitNetwork attack vector

Administrator-level PHP code execution via unescaped ICP write

Published Dec 17, 2025 · Updated Dec 17, 2025

Code injection in ZZCMS 2025 allows remote authenticated users to execute PHP code by submitting a crafted icp website setting. The /admin/siteconfig.php save path writes the icp value into a PHP define statement without neutralizing quote-delimited code. Access to the backend website settings with high privileges is required; successful injection runs in the web application's PHP context.
