Name of the Vulnerable Software and Affected Versions Microsoft Internet Explorer version 8.0 Beta 2

Description The issue allows remote attackers to bypass the product's XSS Filter protection mechanism and conduct cross-site scripting (XSS) and cross-domain attacks. This is achieved by injecting the XDomainRequestAllowed HTTP header after a CRLF sequence, which the product relies on to authorize data exchange between domains.

Recommendations For Microsoft Internet Explorer version 8.0 Beta 2, consider disabling the XDomainRequest feature until a patch is available to prevent exploitation of this issue. Restrict access to external domains to minimize the risk of cross-domain attacks. Avoid using the XDomainRequestAllowed HTTP header in sensitive operations until the issue is resolved.
