CVE-2024-24115Public exploitNetwork attack vector

Administrator access via stored page-editing script

Published Feb 8, 2024 · Updated Jun 17, 2025

Stored XSS in Cotonti CMS 0.9.24 allows remote authenticated users with page-editing rights to execute scripts in visitors' browsers. The Edit Page function stores attacker-supplied markup with the parser set to none, then renders it as active HTML after the parser is switched to html. A moderator or other permitted editor can steal an administrator's session cookie when the administrator views the page and gain administrative access.
