Security updates to Prosys OPC UA products

20.06.2018


We have released updates to our OPC UA Products that have been affected by recently discovered security issues.

The security fixes are in Prosys OPC UA Java SDK 3.1.4 and OPC Foundation Java Stack 1.3.344. OPC UA Client 3.1.4, OPC UA Simulation Server 3.1.4 and OPC UA Modbus Server 1.2.4 are also updated to use the new SDK and Stack to mitigate the potential security issues. All our customers are encouraged to upgrade to these new versions.

If you cannot update, we encourage you to disable Security Policies that have been deprecated in OPC UA 1.04 (Basic128Rsa15 and Basic256). Please read more from the SDK release notes and the following security posts:
