Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the `zone-include.php` script of Revive Adserver version 6.0.7 and below. The application fails to verify CSRF tokens for GET and POST requests that manage the association between banners/campaigns and zones. An attacker can exploit this by inducing an authenticated administrator to visit a malicious webpage or click a link, triggering unauthorized state-changing actions. This allows for the unauthorized linking or unlinking of advertising assets, impacting the integrity and availability of ad delivery configurations.
