OpenSSH 4.3 and PCI Compliance




Posted by skywin, 12-05-2011, 06:45 AM
Hi, we have done a PCI Compliance in a cPanel server and has not completed because openssh 4.3 is considered insecure. Can someone provide more information about this? We use this version. # rpm -qa | grep -i ssh openssh-clients-4.3p2-72.el5_7.5 openssh-4.3p2-72.el5_7.5 openssh-server-4.3p2-72.el5_7.5 Thanks. Last edited by skywin; 12-05-2011 at 06:49 AM.

Who is doing the PCI compliance? It's possible they are using a vulnerability scanner and only seeing that you're using OpenSSH 4.3 which had some vulnerabilities and as such are flagging it as a risk... although your specific version of OpenSSH 4.3p2-72 appears to be OK. You could try upgrading to the latest OpenSSH and see if that helps. Something from the current 5.9 branch. (Just a random guess.)

Is performed by Trustwave, if I change the version of openssh would be a compatibility issue with cPanel?

Make sure to update it using yum so that other dependent packages are upgraded as well. The chances of cpanel running into an issue is very low.

If you change you make sure you manually check for updates on a frequent basis because you won't have the security of just doing a yum upgrade any more.
