Administrator-triggered service disruption via forged group deletion
Published Jul 11, 2023 · Updated Nov 13, 2024
Cross-site request forgery in Issabel PBX 4.0.0-6 allows remote attackers to delete user groups through an administrator's browser. The grouplist endpoint accepts a POST delete action and id_user value without validating a CSRF token, request origin, or referring page. Exploitation requires an authenticated administrator to load attacker-controlled content, after which group deletion can disrupt call routing, access controls, and telephony service.
