Revive Adserver: Reflected XSS on /admin/stats.php

Hi, Security Team!

Linked to the reports:

• https://hackerone.com/reports/1083376
• https://hackerone.com/reports/1097217

In the past reports, we have corrected Reflected XSS. But recently it turned out that with the parameter breakdown = affiliates, this vulnerability still works. (Fixed when parameter breakdown = history).

• Go to http://revive-adserver.loc/admin/stats.php?entity=global&breakdown=affiliates&statsBreakdown=day%27%20onclick=alert(document.domain)%20accesskey=X%20
• For the payload to be executed, the user needs to press the access key combination for the hidden input field (for Firefox, Alt+Shift+X, see this for other browsers).
