Using “Index of ” syntax to find sites enabled with Index browsing

A webserver with Index browsing enabled means anyone can browse the webserver directories like ordinary local directories. Here I shall discuss how one can use “index of” syntax to get a list links to webserver which has got directory browsing enabled. This becomes an easy source for information gathering for a hacker. Imagine if the get hold of password files or others sensitive files which are not normally visible to the internet. Below given are few examples using which one can get access to many sensitive information much easily.

Index of /admin
Index of /passwd
Index of /password
Index of /mail

"Index of /" +passwd
"Index of /" +password.txt
"Index of /" +.htaccess

"Index of /secret"
"Index of /confidential"
"Index of /root"
"Index of /cgi-bin"
"Index of /credit-card"
"Index of /logs"
"Index of /config"

Looking for vulnerable sites or servers using “inurl:” or “allinurl:”

1. Using “allinurl:winnt/system32/” (without quotes) will list down all the links to the server which gives access to restricted directories like “system32” through web. If you are lucky enough then you might get access to the cmd.exe in the “system32” directory. Once you have the access to “cmd.exe” and is able to execute it then Bingo!! You owns the server. ?
2. Using “allinurl:wwwboard/passwd.txt”(without quotes) in the Google search will list down all the links to the server which are vulnerable to “WWWBoard Password vulnerability”. To know more about this vulnerability you can have a look at the following link: http://www.securiteam.com/exploits/2BUQ4S0SAW.html
3. Using “inurl:.bash_history” (without quotes) will list down all the links to the server which gives access to “.bash_history” file through web. This is a command history file. This file includes the list of command executed by the administrator, and sometimes includes sensitive information such as password typed in by the administrator. If this file is compromised and if contains the encrypted unix (or *nix) password then it can be easily cracked using “John The Ripper”.
4. Using “inurl:config.txt” (without quotes) will list down all the links to the servers which gives access to “config.txt” file through web. This file contains sensitive information, including the hash value of the administrative password and database authentication credentials. For Example: Ingenium Learning Management System is a Web-based application for Windows based systems developed by Click2learn, Inc. Ingenium Learning Management System versions 5.1 and 6.1 stores sensitive information insecurely in the config.txt file.

inurl:adpassword.txt
inurl:webeditor.php
inurl:file_upload.php

inurl:gov filetype:xls "restricted"
index of ftp +.mdb allinurl:/cgi-bin/ +mailto

Looking for vulnerable sites or servers using “intitle:” or “allintitle:”

1. Using [allintitle: "index of /root”] (without brackets) will list down the links to the web server which gives access to restricted directories like “root” through web. This directory sometimes contains sensitive information which can be easily retrieved through simple web requests.
2. Using [allintitle: "index of /admin”] (without brackets) will list down the links to the websites which has got index browsing enabled for restricted directories like “admin” through web. Most of the web application sometimes uses names like “admin” to store admin credentials in it. This directory sometimes contains sensitive information which can be easily retrieved through simple web requests.

Other similar search using “intitle:” or “allintitle:” combined with other syntaxs
intitle:"Index of" .sh_history
intitle:"Index of" .bash_history
intitle:"index of" passwd
intitle:"index of" people.lst
intitle:"index of" pwd.db
intitle:"index of" etc/shadow
intitle:"index of" spwd
intitle:"index of" master.passwd
intitle:"index of" htpasswd
intitle:"index of" members OR accounts
intitle:"index of" user_carts OR user_cart

allintitle: sensitive filetype:doc

Conclusion

This is a weird world of internet nothing is secure as anything you make more sophisticated will leads to further weakness or complexities.

In my next article I shall discuss about more advance methods and techniques of Google hacks and how the servers can be secured from it.

About Me

Well, I hail from the world of rules breakers. I love to play with High-End Security Systems and never hesitate to exploit any vulnerability associated with it.

I hack remote servers for the corporates on request and agreement to test their network vulnerabilities. Most of the attacks are done using tools developed by me. Most of these tools are developed using C and C++. Well I believe that as a hacker one must code his/her own tool instead of using some third-party tools. So I have coded few vulnerability scanners for remote host penetration testing. Not so robust, but I like them.

To know more about me you can visit my site: www.hackingspirits.com

Various methods and techniques for penetration testing has been made available on my site: http://www.hackingspirits.com/eth-hac/eth_hac.html

Various tools developed by me are of following categories:

• HTTP Vulnerabilities Scanners
• UDP and TCP scanner for remote port scanning
• Packet sniffers for sniffing and analyzing data and network information
• DOS attacking tools for Denial Of Service test
• Different Brute-Forcing tools
• Remote Access Trojans for talking complete control over the remote host
• Key-loggers with back-doors
