Mitigate your Shell Shock risks in environments using bash

 Already being compared to the heartbleed bug last year, many across the internet are lighting up Linux user forums with tests and comments about “Shell Shock”

Shell shock is a vulnerability in the bash shell terminal that can execute code after a function is called out, and only post authorization via ssh. That said cgi scripting may allow certain other attack vectors and the entire internet is a system of servers that in most cases use bash.

Mac uses it, Linux uses it, Solaris uses it, BSD uses it.

Now essentially the likelihood of worms being developed that can bypass authorization via ssh is fairly high, and the likelihood of more people being duped into allowing privilege escalation is also high.

But this isn’t really as big as it sounds. or it wouldn’t be if there weren’t so many people trying to suggest ways of using the exploit.

I read an article the other day about how to change the root passwords in a Redhat environment, and thought to myself, “Well that was a stupid thing to announce.”

Bash itself will be patched and fixed in a matter of days or weeks in all probability, the kernel updates will erase the potential exploit and we’ll all just breathe easier as usual.

In the meanwhile turn off remote desktop sharing, turn off ssh, turn on your firewalls and if you aren’t using the servers on your system turn those off as well.

There are security programs that can mitigate your risks in Linux environments, Solaris environments and BSD people already know these, namely Tiger to test for vulnerabilities locally. Samhain to detect any incursions, failing that Snort or Suricata. Use a security enhanced kernel if needs be.

Mac users should come and ask questions at Linux forums for technical details regarding how to mitigate their risks.

As for programs that use cgi scripting use a better password system if possible to lock those down. Remember the exploits only work post authorization. So make authorizing menial tasks take higher permissions at a minimum.

I’ve written two books now about these kinds of scenarios and you can find more details about security enhancing Linux, Mac, Solaris, etc here. Because while this particular bug may be a new discovery, it certainly does help to know what steps to take to improve security throughout your systems and infrastructures.

Special thanks to Troy Hunter for posting his article containing this test snippet:

env X=”() { :;} ; echo busted” /bin/sh -c “echo stuff”

Which when executed in bash should read busted if your bash environment is at risk, but be aware that simply running this in a terminal tells you nothing.  (Well it will echo “stuff”) but that isn’t the goal. The goal is to test it via bash itself and see if the system is at risk. Read more about that here.

Linux will be just fine!
