Weblogic - How to Disable TLSv1.3 after Java 1.8.261 update?

in Oracle Weblogic Server (MOSC) 2 commentsAnswered

Hello Everyone,

After we upgraded to JDK 1.8.261, Weblogic automatically started offering TLSv1.3 and that is causing us an issue. (long story)

Is there a way to disable TLSv1.3 and keep TLSv1.2 ONLY?

We tried the option -Dweblogic.security.SSL.protocolVersion=TLSv1.2 to force Weblogic to use TLSv1.2 only, with no success.

I was wondering if we have to change the java.security file and add tlsv1.3 into it. Like below:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, TLSv1.3

Or if there is any other approach to make it.

Thanks!

Fabricio.
