CVE-2019-19135: Use of Insufficiently Random Values

March 16, 2020 (updated July 28, 2021)

In OPC Foundation OPC UA .NET Standard codebase 1.4.357.28, servers do not create sufficiently random numbers in OPCFoundation.NetStandard.Opc.Ua before 1.4.359.31, which allows man in the middle attackers to reuse encrypted user credentials sent over the network.
