Sources and claim methodology

Upstream source description

GFI Archiver before 15.14 contains a stored cross-site scripting vulnerability in the MailInsights scheduled report configuration that allows authenticated attackers to inject arbitrary web script or HTML via the report name parameter to /Archiver/MailInsights.aspx. The injected payload is stored by ReportScheduling.btnSaveReport_Click() without output encoding and is executed in the browser of the user who created the scheduled report when they subsequently view the MailInsights page.
