would it be worth it to take the linux one and move it to a multi, then add this in? Having not looked at the code, I would assume there is a lot of overlap

Also, please try msftidy_docs from #12878 it should help with some consistency issues

[WARNING] Docs should start with ## Vulnerable Application
[WARNING] Missing Section: ## Vulnerable Application
[WARNING] H2 headings in incorrect order. Should be: Vulnerable Application, Verification Steps, Options, Scenarios

@h00die I've sorted the rest of the issues but do we think these warnings make sense for post modules? There isn't really a vulnerable application in this case at least
