The cross-site scripting vulnerability could allow an intruder to execute code in the security context of the currently logged on user.

A spoofing attack could take place because input provided to HTML redirection queries is not adequately validated before the input is sent to a user's Web browser.


Microsoft has released Security Bulletin MS05-006, "Vulnerability in Windows SharePoint Services and SharePoint Team Services Could Allow Cross-Site Scripting and Spoofing Attacks (887981)," and a patch to correct the problem.
