CVE reference:CVE-2006-0032


Description:
Eiji James Yoshida has reported a vulnerability in Microsoft Windows, which can be exploited by malicious people to conduct cross-site scripting attacks.

UTF-7 encoded input is not properly sanitised by the Indexing service before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session.

Successful exploitation requires that the Indexing service is accessible through IIS.

Solution:
Apply patches.
