Download Free XSS Shell v0.3.9 - (Xss)Cross Site Scripting Backdoor Tool

XSS Shell is a powerful XSS backdoor which allows interactively getting control over a Cross-site Scripting (XSS) vulnerability in a web application. Demonstrates the real power and damage of Cross-site Scripting attacks.
WHAT IS XSS SHELL ?XSS Shell is powerful a XSS backdoor and zombie manager. This concept first presented by XSS-Proxy (XSS-Proxy: A tool for realtime XSS hijacking and control). Normally in XSS attacks attacker has one shot, in XSS Shell you can interactively send requests and get responses from victim, you can backdoor the page.You can steal basic auth, you can bypass IP restrictions in administration panels, you can DDoS some systems with a permanent XSS vulnerability etc. Attack possibilities are limited with ideas. Basically this tool demonstrates that you can do more with XSS.FEATURES
XSS Shell has several features to gain whole access over victim. Also you can simply add your own commands.
Most of the features can enable or disabled from configuration or can be tweaked from source code.
  • Regenerating Pages
  • Keylogger
  • Mouse Logger (click points + current DOM)
Built-in Commands:
  • Get Keylogger Data
  • Get Current Page (Current rendered DOM / like screenshot)
  • Get Cookie
  • Execute supplied javaScript (eval)
  • Get Clipboard (IE only)
  • Get internal IP address (Firefox + JVM only)
  • Check victim’s visited URL history
  • DDoS
  • Force to Crash victim’s browser
  Install Admin Interface;

1. Copy "xssshell" folder into your web server
2. Copy "db" to a secure place (below root)
3. Configure "database path" from "xssshell/db.asp"
4. Modify hard coded password in db.asp [default password is : w00t]
5. Now you can access admin interface from something like http://[YOURHOST]/xssshell/

Configure XSS Shell for communication;
1. Open xssshell.asp
2. Set "SERVER" variable to where your XSSShell folder is located. i.e: "http://[YOURHOST]/xssshell/";
3. Be sure to check "ME", "CONNECTOR", "COMMANDS_URL" variables. If you changed filenames, folder names or some kind of different configuration you need modify them.

Now open your admin interface from your browser,
To test it, just modify "sample_victim/default.asp" source code and replace "http://attacker:81/release/xssshell.js" URL with your own XSS Shell URL. Open "sample_victim" folder in some other browser and may be upload in to some other server.

Now you should see a zombie in admin interface. Just write something into "parameters" textarea and click "alert()". You should see an alert message in victim's browser.

- As a hunter be careful about possible "Backfire" in getSelfHTML(). Someone can hack you back or track you by another XSS or XSS Shell attack.
    - Checkout "showdata.asp" and implement your own "filter()" function to make it safer for you.

- Put "On error resume next" to db.asp, better modify your web server to not show any error.

First implement it to xssshell.asp
    1) Add new enum for your control
        - Set a name and unique number like "CMD_GETCOOKIE"
            - var CMD_SAMPLE = 78;
        - Set datatype for your response (generally TEXT),
            - dataTypes[CMD_SAMPLE] = TEXT;
    2) Write your function and add it to page
        - function cmdSample(){return "yeah working !"}
    3) Call it
        - Go inside to "function processGivenCommand(cmd)"
        - Add a new case like "case CMD_SAMPLE:"
    4) Report it back
        - Inside the case call log;
        "log(cmdSample(), dataTypes[cmd.cmd], cmd.attackID, "waitAndRun()");"
Secondly Implement it to admin interface;
    - In db.asp just add a new element to "Commands" array (command name, command unique number, description).
    i.e. "cmdSample()",78,"Command sample ! Just returns a message"

There are parameters and lots of helper in the code. Check out other commands for reference.
Enable debug feature to debug your new commands easily.
- Keylogger is not working on IE
- Possibly not going to work for framed pages because of frame regeneration.
- Not working on Konqueror
