Description

An access control bypass allows an advertiser‑level user to activate or deactivate a banner in Revive Adserver 6.0.6 and earlier, even when such permissions were not granted. The banner-edit.php script allowed the banner status to be overwritten solely based on banner edit permissions. The status field has been removed from the hidden form fields in the banner edit screen.
