2007-10-15: Email with notification sent to ifnet.it

____________________
|| 0x02: INFORMATION

In the WEBIF product by the italian company ifnet, an error
occurs due to the fact of an unfiltered variable (cmd) in the
webif.exe program. It is possible to execute any JavaScript code
by manipulating the parameter.

_____________________
|| 0x03: EXPLOITATION

To exploit this bug no exploit is needed, all can be done through
manipulation of the given URL:

STEP 1:
Go to the standard page of the WEBIF product, normally existing
at "/cgi-bin/webif.exe". You will recognize some further parameters,
being "cmd", "config" and "outconfig".

STEP 2:
Don't change any parameter instead of the "cmd" one. Change its value
to any JavaScript code you like. For our demo we will use the default
one, being "<script>alert('XSS');</script>".

STEP 3:
Click ENTER and execute the code. A successfull demonstration will
popup a window.

EXAMPLE:
http://example.com/webif/cgi-bin/webif.exe?cmd=<script>alert('XSS');</script>&config=[ * ]&outconfig=[ * ]

[ * ] = Depends on the server. Don't change this!
