I did the test of https://www.ssllabs.com/ssltest/ and my grade it was F.
Look at this message:
Zimbra - this server is vulnerable to the openssl padding oracle vulnerability (cve-2016-2107) and insecure.
How can I fix this?

Re: Zimbra SSL Labs F Grade
You should always give the full output of the followind command:
If you're not on the current version then I'd suggest you upgrade.
Code: Select all
xmcontrol -v

Thanks my friend, I fixed that problem with this:
Corrigir OpenSSL padding oracle in AES-NI CBC MAC check (CVE-2016-2107)
Edit /opt/zimbra/.bash_profile - add the following to the end of user zimbra's .bash_profile (requires root privs):
# workaround CVE-2016-2107
export OPENSSL_ia32cap="~0x200000200000000"
Edit sudoers - add the following line to your sudoers (/etc/sudoers or whatever is appropriate for your platform):
Defaults env_keep += "OPENSSL_ia32cap"
Configure postfix - instructs postfix to honor the desired environment variable:
$ zmlocalconfig -e postfix_import_environment='OPENSSL_ia32cap'
But now, I need resolve another issue:
This server supports anonymous(insecure)suites(see below for details). Grade set to F.
This server supports weak Diffie-Hellman(DH) key exchange parameters. Grade capped to B.

Re: Zimbra SSL Labs F Grade
Good morning I resolved my problem updating to the Zimbra 8.8.8 version.
Now my current grade is A.
