CVE-2024-35110Public exploitNetwork attack vector

Cookie theft via unescaped login redirect

Published May 17, 2024 · Updated Feb 13, 2025

Reflected XSS in YzmCMS 7.1 allows remote attackers to capture a logged-in user's cookies through a crafted login URL. The login flow copies the referer parameter into $gourl, and message.tpl inserts that value into a meta tag without complete HTML escaping. A victim must be logged in and open the malicious link; injected browser script can read cookies available to client-side code.
