Technical details

Stored cross-site scripting (CWE-79) in the MailInsights scheduled report configuration allows authenticated users to inject arbitrary HTML/JavaScript via the report name parameter to /Archiver/MailInsights.aspx. The ReportScheduling.btnSaveReport_Click() method stores the payload without output encoding, executing it when the report creator or other users view the MailInsights page. An attacker with valid credentials can exploit this to compromise other users' sessions.
