Id Description
74406 Microsoft Windows Remote Desktop Web Access Logon Page Unspecified XSS

Microsoft Windows Remote Desktop Web Access contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate certain unspecified input to the Logon page before returning it to the user. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
