Issue/Introduction

VA scan detected "TLS Version 1.0/1.1 Protocol Detection" vulnerability on TCP 8443 on CA PIM 14.0 on Windows Server 2016.

Environment

Release : 14.0

Component : ENTM

Resolution

This vulnerability is resolved by disabling TLSv1.0 and TLSv1.1 in the java.security under jdk.tls.disabledAlgorithms.

From jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768
To jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, MD5withRSA, DH keySize < 768

!!! You may add or remove respective algorithms to meet your needs. This is a demonstration of how it can be done for TLS v1.0 and TLS 1.1

Restart of tomcat/jboss is required.

Additional Information

Note: The following is only focusing on removal of TLS 1.0 and 1.1.
For SWEET32 and DH Key issue please refer to KB191950
