I'm trying to write an Ansible task to check for both CVE-2014-6271 and
CVE-2014-7169 as I haven't been able to find one pre-made.
This command should check both but for the life of me I can't get the
escaped single quote past the parser... I've tried some variants of "shell:
>" and "shell: |" but no dice.
- name: Check for shellshock fix (checks for both CVE-2014-6271 and
> CVE-2014-7169)
> shell: cd /tmp && rm -f /tmp/echo && env 'x=() { :;}; echo vulnerable'
> 'f=() { (a)=>\' bash -c 'echo echo vulnerable'; cat echo
> args:
> executable: /bin/bash
> sudo: no
> register: shellshock_result2
> changed_when: False
> failed_when: "'vulnerable' in shellshock_result2.stderr"
>
This version gives:
ERROR: There was an error while parsing the task "shell cd /tmp && rm -f
/tmp/echo && env 'x=() { :;}; echo vulnerable' 'f=() { (a)=>\\' bash -c 'echo
echo vulnerable'; cat echo".

I'm assuming the issue is that, if I understand correctly, the second
exploit partly depends on the mismatched quote arriving unharmed(?) and
YAML thinks that is bad(?).
Anyone have any ideas or should I just copy it over as a script and run
that?
Thank you,
Mark
