CVE-2024-23031Public exploitNetwork attack vector

Administrator cookie theft via reflected is_water input

Published Feb 1, 2024 · Updated Jun 4, 2025

Reflected XSS in EyouCMS 1.6.5 allows remote attackers to execute script in an administrator's browser through a crafted upload-list URL. The admin upload-list route decodes attacker-controlled JWT header data from the info query parameter and inserts is_water directly into an HTML input value without neutralization. Exploitation requires a logged-in administrator to visit the URL, allowing the injected script to steal that administrator's session cookie.
