SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/20825/

CRITICAL:
Less critical

IMPACT:
Exposure of sensitive information, System access

WHERE:
From remote

SOFTWARE:
Microsoft Internet Explorer 6.x
http://secunia.com/product/11/

DESCRIPTION:
Plebo Aesdi Nael has discovered two vulnerabilities in Internet
Explorer, which can be exploited by malicious people to disclose
potentially sensitive information and potentially compromise a user's
system.

1) An error in the handling of redirections can be exploited to
access documents served from another web site via the
"object.documentElement.outerHTML" property.

Secunia has constructed a test, which is available at:
http://secunia.com/internet_explorer_information_disclosure_vulnerability_test/

2) An error in the handling of file shares can be exploited to trick
a user into executing a malicious HTA application via directory
traversal attacks in the filename.

Successful exploitation requires some user interaction.

The vulnerabilities have been confirmed on a fully patched system
with Internet Explorer 6.0 and Microsoft Windows XP SP2. Other
versions may also be affected.

SOLUTION:
1) Disable Active Scripting support.

2) Filter Windows file sharing traffic.
