HackerOne community member Patrick Lang (7yr) has reported a reflected XSS vulnerability in the `banner-acl.php` and `channel-acl.php` scripts of Revive Adserver. An attacker can craft a specific URL that includes an HTML payload in a parameter. If a logged in administrator visits the URL, the HTML is sent to the browser and malicious scripts would be executed.
