In order to run it we just need to make one change to the PoC script. Once you have the Lync 2013 SDK installed, go ahead and grab the CVE-2018-8474 PoC script here. Karl Fosaaen over at NetSPI has a great write-up on getting this started, and I recommend you follow the steps in his post here:

This is easy вЂ“ simply download the Microsoft Lync: Mac 2011 client, open it, and sign in.ДЇirst, youвЂ™ll want to set up the Lync 2013 PowerShell SDK. To test the vulnerability, you will need an attacking machine (a Windows host that can run PowerShell), and a target machine (a Mac with the Lync Mac 2011 client running). If you go to the Skype for Business 2016 Mac client download page you see that they recommend using the Lync 2011 client when connecting to Lync Server 2010. With that being said, if they donвЂ™t want to fix it, Microsoft should stop recommending it and remove it from their downloads page.

Plus, itвЂ™s the Mac client, so the install base is likely on the smaller side. Lync: Mac 2011 is an aging client, with two product replacements out for it already (Skype for Business, and the new Microsoft Teams). IвЂ™m not completely surprised by their decision not to fix the problem. The Microsoft Security Advisory can be found here:

September, 11 2018 вЂ“ Microsoft discloses existence of vulnerability CVE-2018-8474.

July 2018 вЂ“ Microsoft has decided they wonвЂ™t be publishing fix after all.

May 2018 вЂ“ Microsoft decides to fix it after all.

April 2018 вЂ“ File with MITRE for CVE, MITRE contacts Microsoft.

March 2018 вЂ“ Microsoft decides not to fix.

November 2017 вЂ“ Microsoft has been able to replicate issue.I reported this to Microsoft in July 2017 and the MSRC opened a ticket. While tags were blocked, and various other JavaScript injections failed, I discovered that an tag would spawn a browser session to the target URL.ДЄ slightly less-useful trick is to embed an image directly into the chat by sending tags:Дisclosure Timeline and MicrosoftвЂ™s Response This successfully modified the message formatting, so I then extended testing to other HTML tags. To begin with, I experimented with sending or tags to style the text. I used вЂPowerSkypeвЂ™ by Karl Fosaaen of NetSPI as a base ().

It is the result of a failure to sanitize input that is taken in via the Lync 2013 PowerShell SDK.
