CVE-2023-29815Network attack vector

Account and configuration changes via missing CSRF validation

Published Apr 28, 2023 · Updated Jan 30, 2025

CSRF in chshcms mccms 2.6.3 allows remote attackers to trigger account, balance, and configuration changes through a user's browser. The front-end user-information and administrative actions accept state-changing requests without a CSRF token or Referer validation. An authenticated user must be induced to submit the forged request; an administrative session exposes administrator creation, user-balance changes, and site-configuration changes.
