Resolving Bash vulnerability in InterWorx servers : How to fix CVE-2014-6217 Bash “Shell Shock” vulnerability

[UPDATE 1st Oct] – More vulnerabilities were reported since this post was originally written on Sep 26th. See the notes at the bottom.

Highly critical Bash code injection vulnerability CVE-2014-6217 was declared on 24th Sep, and a patch is now available for InterWorx servers.

If you have a InterWorx server, it has Bash, and if you haven’t expressly patched it, assume that your server is vulnerable to hack. InterWorx servers are typically enabled with CGI modules, and they could allow commands to be passed on to Bash, thus opening the gates to hackers.

The engineers in our Proactive Server Management Services detected this threat on 24th, and patched all our InterWorx servers with the following steps:

In CentOS / Fedora / RedHat / CloudLinux servers,

Login to terminal as root and execute the command:

# yum -y update bash

If you are not comfortable executing commands as root, consult a systems administrator.

This should protect you from the critical CVE-2014-6217 vulnerability, however, your server will need to be patched again to be fully protected once a solution is available for the related CVE-2014-7169 vulnerability. We will update this post when a patch is available. When it is released, just execute the above steps again.

[ UPDATE ] – Patch for CVE-2014-7169 is now available. So, in case you have already ran the commands above, re-run them again to get the final patch. 

Critical vulnerabilities are a fact of web hosting. Bobcares Proactive Server Management prevents zero-day exploits by configuring servers for managed auto-upgrades.
