In Progress® Telerik® Report Server prior to version 12.2.26.1007, a stored cross-site scripting vulnerability in the shared reporting engine allows an authenticated report author to embed javascript: or vbscript: URLs in report navigation actions or HTML text box links. When another user views the malicious report and the embedded navigation is triggered, attacker-controlled script can execute in the web report viewer's origin. In a multi-user Report Server deployment, this can enable privilege escalation by performing actions in a higher-privilege user's authenticated session, including an administrator's session.
