Microsoft Internet Explorer Cookie Path Attribute Vulnerability Advisory Available in Danish 

Secunia Advisory: SA13208  
Release Date: 2004-11-17
Last Update: 2005-02-21

Critical:
Not critical
Impact: Hijacking
Where: From remote
Solution Status: Partial Fix

Software:Microsoft Internet Explorer 6.x

CVE reference:CVE-2004-1527 (Secunia mirror)



Description:
Keigo Yamazaki has reported a vulnerability in Internet Explorer, which potentially can be exploited by malicious people to conduct session fixation attacks.

The vulnerability is caused due to a validation error in the handling of the path attribute when accepting cookies. This can potentially be exploited by a malicious website, if the trusted site supports wildcard domains or the domain name contains the malicious sites domain, using a specially crafted path attribute to overwrite cookies for the trusted site.

The vulnerability has been reported in Internet Explorer 6.0 SP1 on Microsoft Windows XP SP1. Microsoft Windows XP SP2 is reportedly not affected.

Note: Successful exploitation also requires that the trusted site handles cookies and authentication in an inappropriate or insecure manner.

Solution:
Update to Windows XP SP2.

Disable cookies except when needed.
