From the README.md

**When a user connect to vpn,** vpndownloader.exe process is started in background and it will create directory in c:\windows\temp with default permissions in following format: <random numbers>.tmp After creating this directory vpndownloader.exe will check if that directory is empty and if its not it will delete all files/directories in there. This behaviour can be abused to perform arbitrary file delete as NT Authority\SYSTEM account.

Yes, the exploit relies on vpndownloader.exe to be processed via connection.

Thank you @ThisGuyNeedsABeer! Do you know if it must be a successful authentication though? Or is just the act of connecting to an anyconnect VPN appliance enough to trigger the vpndownloader.exe process to execute?
