Description:
Derek Abdine has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to conduct FTP command injection attacks.
The vulnerability is caused due to an input validation error when processing FTP URIs. This can be exploited to inject arbitrary FTP commands in a FTP session using e.g. a specially crafted FTP URI containing CRLF character sequences and trailing slashes.
Successful exploitation requires that a user e.g. is tricked into visiting a malicious website.
The vulnerability is confirmed in version 6.0.2900.2180 and also reported in version 5. Other versions may also be affected.
Solution:
Upgrade to Internet Explorer 7. Do not browse untrusted websites.
