DescriptionA stored XSS vulnerabilities exists in the `maintenance-acl-check.php` and `maintenance-banners-check.php` tools of Revive Adserver 6.0.7. The issue was caused by entity names being displayed without proper escaping when inconsistencies were detected. Whether the XSS payload is executed when an administrator uses the affected maintenance tools is not entirely under the attacker's control.
