Technical details
An improper access control vulnerability (CWE-284) exists in Revive Adserver versions 6.0.6 and earlier within the banner-edit.php script. The application incorrectly allowed the banner status to be overwritten based solely on general banner edit permissions rather than specific status-change authorizations. This was facilitated by the inclusion of the status field in hidden form fields on the banner edit screen, which could be manipulated by an authenticated advertiser-level attacker. The vulnerability has been addressed by removing the status field from the hidden form fields in the banner edit interface.
