Rooted. What a pain in the ■■■ this box was. Did anyone manage “NOT” to use a separate VM windows box for that “yso” tool?? I had more problems setting up a VM than I did rooting this box. If you manage to create a payload without windows machine, please let me know. Thank you

I used vi with payload by adjusting array item, encoding output and pasted into burp. What was odd was the final payload I needed to add an extra white space at the beginning for it to execute ie after /c . No idea why the double white space worked but single failed every time.
No windows required just create a bash script with above
