Summary
Cotonti CSRF in admin.rights.php allows privilege escalation
Details

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the administration rights handler. In system/admin/admin.rights.php, the rights update action ('a=update') modifies group access rights (including via cotauthaddgroup) without calling cotcheck_xg to validate the anti-CSRF token.
