Descriptions

Revive Adserver before 5.1.0 is vulnerable to a reflected cross-site scripting (XSS) vulnerability via the publicly accessible afr.php delivery script. While this issue was previously addressed in modern browsers as CVE-2020-8115, some older browsers (e.g., IE10) that do not automatically URL encode parameters were still vulnerable.

Si bien este problema se abordó anteriormente en los navegadores modernos como CVE-2020-8115, algunos navegadores antiguos (por ejemplo, IE10) que no codifican automáticamente los parámetros de la URL seguían siendo vulnerables

Revive Adserver versions 5.0.5 and below suffer from persistent and reflective cross site scripting and open redirection vulnerabilities.
