Command Injection Exploitation using Web Delivery (Linux, Windows)

Hello friends! In this article you will learn how to exploit three different platforms [Linux, windows, using a single exploit of the Metasploit framework.

Requirement

Attacker: Kali Linux

Targeted Platform: Window,PHP,Linux [ubuntu]

Open the terminal in your Kali Linux and type “msfconsole” to load Metasploit framework and execute given below exploit.

This module quickly fires up a web server that serves a payload. The provided command which will allow for a payload to download and execute. It will do it either specified scripting language interpreter or “squiblydoo” via regsvr32.exe for bypassing application whitelisting. The main purpose of this module is to quickly establish a session on a target machine when the attacker has to manually type in the command: e.g. Command Injection, RDP Session, Local Access or maybe Remote Command Execution. This attack vector does not write to disk so it is less likely to trigger AV solutions and will allow privilege escalations supplied by Meterpreter. When using either of the PSH targets, ensure the payload architecture matches the target computer or use SYSWOW64 powershell.exe to execute x86 payloads on x64 machines. Regsvr32 uses “squiblydoo” technique for bypassing application whitelisting. The signed Microsoft binary file, Regsvr32, is able to request an .sct file and then execute the included PowerShell command inside of it. Both web requests…
