RE: IIS 3.0 pen-test

Well besides the rest of the vulnerabilites with MS IIS 3.0, I tested the
servers for Unicode and it seemed they were vulnerable. ( I check using a
perl script that I found on Packetstorm) it discovered that the servers
were
vulnerable to various forms of the unicode vulnerability.

The perl script you have checks for the word directory in the response from
the server
So when your getting back the error: 

saying "HTTP/1.0 403 Access Forbidden (Execute Access Denied -This Virtual
Directory does not allow objects to be executed.)"

your perl script thinks its vulnerable.  

This is a piece of code taken from a perl script that check for unicode.

(taken from unicodeloader.pl)
my @results=sendraw("GET $uni+dir HTTP/1.0\r\n\r\n");
 foreach $line (@results){
  if ($line =~ /Directory/) { # THIS LINE IS GENERATING YOUR FALSE POSITIVE.
