RE: Google lists vulnerable sites.

["Erick Arturo Perez Huemer" <eperez () compuservice net>]

Doing a query of a specific country/language and using inurl:iisadmin
revealed a simple list of sites running the Internet Information Server
administrator page, the list returned was 45. Of those, 9 had no
password and were visible from my side.

Several searches can be made: Ports in the url, specific cgi, specific
files (like the db) etc.

Using the db as an example, I was able to see several sites that use a
web program to manage statistics and other data. Those sites were under
an obfuscated URL and I guess they were supposed not to be seen by the
outsiders.

The only drawback is that I do not seem to be able to define a "set" of
ip addresses rather than domains to search.

Google.com.....Simple Nmap's rival?? (it´s a joke, dont start
blaming....)

The above search sets the requirments that admin must be in the url and 
only sites that contain a file of the type .db are returned.

Now most of the links you click on will take you to some meaningless url

or email database but if for exaple you had

www.somesite.org/admin/cgi-bin/url.db

and you removed the url.db from the link you are now free to traverse 
through there directories and files.  By useing carefully selected
search 
terms like the ones above I have about a 90-95% success rate of 
vulnerable sites returned.  The trick is finding the right directory and

filetypes to use in the search.
