Are you Shellshock(ed)?

The Shellshock bash bug is a critical security hole for all Unix, Linux and *nix based systems. Bash(Unix Shell) is a piece of Software released by Brian Fox in 1989 for the GNU Project.

The bug can affect you trough malicious requests sent to web servers or network devices.

A number of Cisco products use an affected version of the Bash shell.

Cisco made an official statement that meraki devices are not affected from the Shellshock and Heartbleed vulnerability. See detailed information at the official cisco website.
