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.
