What is it?
Shellshock impacts a Linux-based program called Bash that is incorporated into many other technologies – from network routers to websites. That does not mean that all of them are vulnerable. Vulnerability depends on how the Bash code is accessed. In certain cases, the way the Bash code is accessed creates an opening for hackers to access your systems and steal information.
If you are looking for a good "Shellshock 101" primer, this article concisely explains the Shellshock vulnerability, why most end users are not impacted directly, and how to protect your systems.
