XProtect® VMS: .NET security vulnerability (hotfixes for 2016 R1 - 2018 R1)& XProtect®: .NET security vulnerability

The Recording Server, Management Server and Management Client in XProtect® (Corporate, Expert, Professional+, Express+, Essential+) use an exploitable .NET Framework Remoting deserialization level. Elevation of Privileges and/or Denial-of-Service are possible if the affected ports are exposed. 

Hotfixes have been released for versions 2016 R1 (10.0a) through 2018 R1 (12.1a) and the issue is fixed permanently in 2018 R2 (12.2a). Systems running an XProtect version older than 2016 R1 must upgrade to the 2016 R1 product version or later and apply the relevant patch to mitigate this vulnerability. It is recommended to install the hotfixes if you use any of the affected XProtect products.

For more information (list of ports, etc.), check KB 4218, "XProtect®: .NET security vulnerability."

Please note that only XProtect products from the C-code group are affected: Corporate, Expert, Professional+, Express+, Essential+. The E-code products (Professional, Express) are not affected.
