  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Enabled all pci compliance options, still failing CVE-2011-3389: SSL/TLS Protocol x 3

New Pleskian
Hi.

I have latest Plesk 9.5.x updates

I have enabled the pci-compliance options

/usr/local/psa/admin/bin/pci_compliance_resolver --enable all

and followed the Plesk guide

Securing Servers in Compliance with PCI Data Security Standard - http://download1.parallels.com/Plesk...mpliance-guide

It passes everything now except 3 failures - they are all related to SSL/TLS...

SSL/TLS Protocol Initialization Vector
Implementation Information Disclosure
Vulnerability imap (143/tcp)
CVE-2011-3389

SSL/TLS Protocol Initialization Vector
Implementation Information Disclosure
Vulnerability pop3 (110/tcp)
CVE-2011-3389

SSL/TLS Protocol Initialization Vector
Implementation Information Disclosure
Vulnerability https (443/tcp)
CVE-2011-3389

It seems related to SSL, I have disabled weak ciphers as outlined in the guide.

How can I get this to pass ?

Any help is welcomed
 
I agree, the same issue here with new PCI compliance scan. We need solution.
 
Edit /etc/courier-imap/*-ssl and look for the TLS_CIPHER_LIST line; replace it with this:

Code:
TLS_CIPHER_LIST="ALL:!ADH:RC4+RSA:-SSLv2:+HIGH:+MEDIUM:-LOW:-EXP:@STRENGTH"

Then restart courier.
 
ok - that didn't work.

I assume it is because I had used the Plesk tool to PCI comply the server

i.e

/usr/local/psa/admin/bin/pci_compliance_resolver --enable courier

- this creates

/etc/courier-imap/imapd-ssl.pci
/etc/courier-imap/pop3d-ssl.pci

Which contains

TLS_CIPHER_LIST="HIGH:MEDIUM:!SSLv2:!LOW:!EXP:!aNULL:mad:STRENGTH"

Is this conflicting ?

Try replacing that one with the string I sent and restart courier. It took me a while to find the right combination of arguments that make the pci scanning companies happy.
