Name of the Vulnerable Software and Affected Versions Revive Adserver versions prior to 5.2.0

Description The issue allows an attacker to execute injected JavaScript code by tricking a user into clicking on a specifically crafted URL. This is due to a reflected XSS vulnerability in the status parameter of the "campaign-zone-zones.php" endpoint.

Recommendations For versions prior to 5.2.0, update to version 5.2.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the "campaign-zone-zones.php" endpoint to minimize the risk of exploitation. Avoid using the status parameter in the affected endpoint until the issue is resolved.
