Name of the Vulnerable Software and Affected Versions Microsoft Exchange Server 2013 SP1 and Cumulative Update 7

Description A cross-site scripting (XSS) issue exists in the errorfe.aspx page of Outlook Web App (OWA) in Microsoft Exchange Server, allowing remote attackers to inject arbitrary web script or HTML via the msgParam parameter in an authError action.

Recommendations For Microsoft Exchange Server 2013 SP1 and Cumulative Update 7, consider restricting access to the errorfe.aspx page until a patch is available. As a temporary workaround, avoid using the msgParam parameter in the authError action to minimize the risk of exploitation.
