Vulnerability details
The vulnerability allows a remote user to modify HAProxy routing policies, disrupt service, and potentially expose traffic within the user's active group.
The vulnerability exists due to missing action-level authorization in the Roxy-WI /add/map endpoint when handling map modifications and service actions. A remote user can use a read-only role-4 session with HAProxy access and a valid CSRF token to submit map content and map_restart=reload or map_restart=restart, uploading a controlled map and triggering privileged service actions to alter forwarding behavior or disrupt availability.
