Microsoft IIS 5/6 FTP 0Day released

We are aware of an new 0-day exploit that was posted on Milw0rm today.

According the exploit, it was suppose to work on both IIS 5.0 and 6.0, on the FTP module.

The latest on this is that HDMoore is porting it to the MetaSploit framework.

We will update this diary with more info as we get it.
