I understand that I need to remove two of them:

how do i do?
openssl ciphers ....... ??
disabling CBC mode ciphers
--------------------------
Key: WFLY-3451
URL: https://issues.jboss.org/browse/WFLY-3451
Project: WildFly
Issue Type: Sub-task
Security Level: Public(Everyone can see)
Affects Versions: JBoss AS7 7.1.1.Final
Reporter: Aleksandr Voloschuk
Assignee: Darran Lofthouse
Priority: Critical
encountered such a problem:
management of information security vulnerability found on a production environment,
namely:
SSLv3.0/TLSv1.0 Protocol Weak CBC Mode Vulnerability port 8443/tcp over SSL
RC4-SHA ECDHE-RSA-DES-CBC3-SHA SSLv3
they offer a solution:
This attack was identified in 2004 and later revisions of TLS protocol which contain a
fix for this. If possible, upgrade to TLSv1.1 or TLSv1.2. If
upgrading to TLSv1.1 or TLSv1.2 is not possible, then disabling CBC mode ciphers will
remove the vulnerability. Setting your SSL server to prioritize RC4 ciphers mitigates this
vulnerability.
as TLS upgrade we can not, it remains disabling CBC mode ciphers
our platform is jboss-eap-6.1
