Administrator creation via cross-origin member request
Published Mar 4, 2022 · Updated Jul 9, 2026
Cross-site request forgery in the Members administrator function of Intelliants Subrion CMS 4.2.1 allows remote attackers to create administrators. The add-member endpoint accepts a victim administrator's cross-origin POST to /panel/members/add/ and honors attacker-chosen account fields, including usergroup_id 1. Exploitation requires an authenticated administrator to submit the crafted form; the resulting active account has administrator privileges.
