Today a new SSL/TLS vulnerability has been made public which uses the old EXPORT ciphers to drive MITM (Man-in-the-middle) Attacks.
The check for all of you!
I've tested all my private and business machines which are not vulnerable and made a nagios-compatible check for that. You can run it with Nagios or Icinga to check multiple services at once or use the check on the command-line to check them once.
You can find the check as a Github Gist here. If have any problems or enhancements, let me know!
