Administrator-session user deletion via missing CSRF validation
Published Jun 20, 2023 · Updated Dec 10, 2024
Cross-site request forgery in Neeke HongCMS 3.0.0 allows remote attackers to delete users through an administrator's browser. The administrative user-management endpoint accepts deleteuserids and updateuserids parameters without validating that the administrator intended the request. An authenticated administrator must open an attacker-controlled link, after which the selected account is deleted; the published demonstration does not establish code execution or privilege escalation.
