      Description

      SSHD is setup with unsecured cyphers like CBC (see https://www.kb.cert.org/vuls/id/958563). These cyphers should be removed.

      There is already a PR filed here: https://github.com/jenkinsci/sshd-module/pull/5. This will also need to be integrated in core hence this ticket.

            Ideally also makes sense to add new Ciphers, but it is blocked by JENKINS-33021

            The fix has been integrated into 3.34 as an RFE.
            If you consider it as a bug fix, please respond

            Oleg Nenashev Daniel BeckAllan BURDAJEWICZ Maybe we should propose to backport it into 2.32.x (as it is a security fix/improvement). WDYT ?
