Running CVE-2017-8759 exploit sample.
Flow of the exploit:
Word macro runs in the Doc1.doc file. The macro downloads a badly formatted txt file over wsdl, which triggers the WSDL parser log. Then the parsing log results in running mshta.exe which in turn runs a powershell commands that runs mspaint.exe
To test:
Run a webserver on port 8080, and put the files exploit.txt and cmd.hta on its root. For example python -m SimpleHTTPServer 8080
If all is good mspaint should run.
