Internet Explorer FTP Download Directory Traversal

   
Internet ExplorerAlbert Puigsech Galicia has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an input validation error in the handling of FTP file transfers. This can be exploited by a malicious FTP server to create files in arbitrary locations via directory traversal attacks by tricking a user into downloading malicious files (e.g. by dragging or copying a file or folder).

The vulnerability has been confirmed on a fully patched system with Internet Explorer 6.0 and Microsoft Windows 2000 SP4 / XP SP1.

SOFTWARE:
Microsoft Internet Explorer 5.01
Microsoft Internet Explorer 5.5
Microsoft Internet Explorer 6

SOLUTION:
The vulnerability does not affect systems running Windows XP with SP2 installed.

Do not download files from untrusted FTP servers.
