SecurityNotFound Save
🐚 404 Page Not Found Webshell
📼 Clone me!
Clone or download the project:
git clone --depth=1 https://github.com/CosasDePuma/SecurityNotFound.git
📦 "Installation"
The src/404.php file should be located on the target server and it must have the ability to execute .php files.
Here is an example of some of the most common routes on which servers are located:
# 🏁 Windows
C:\Xampp\htdocs\ # Xampp
# 🐧 Linux
/var/www/html/ # Apache
/usr/share/nginx/html/ # Nginx
👮 Obviously, you and I know that you have legitimate access to that server.
🚪 Access Granted!
Now, you can access it through the browser:
https://www.example.com/404.php
💡 You can replace the server 404 error template to access from any invalid URL.
To access the control panel, press TAB key or search the password field using your browser's tools:
The default password is: cosasdepuma.
🥚 You can leave the
$passphrasevariable in the script as an empty string to directly access the control panel.
🔒 To set a custom value, insert your password into the
$passphrasevariable after applying theMD5algorithm three consecutive times.
🎮 Control Panel
Once logged in, the webshell will show its real appearance:
The panel features an AJAX console and a number of preconfigured actions:
| Name | Description |
|---|---|
| PHP Info | Shows phpinfo(); page. |
| Geolocate | Shows in Google Maps the place where the server is physically located. |
| Exploit-DB (...) | Searches for compatible exploits in exploit-db.com. |
| Log out | Exits the dashboard. |
It should be noted that the execution of commands is performed using the "Referrer" header, its content being the executed payload.
This has two advantages: greater stealth within the log file and the ability to execute commands without the need to access the web interface.
