How does Shellshock work?
Fedora Magazine has details about how the Shellshock Bash vulnerability works.
According to Fedora Magazine:
By now, you’ve probably seen this magic incantation, or variations, sent all around as a quick test for vulnerability to CVE-2014-6271, known as “Shellshock”, because in this post-Heartbleed world, apparently all security flaws will have cute over-dramatic names.
But, why is code in environment variables getting executed? Well, it’s not supposed to be — but, because of a feature which I’m tempted to call a bit too clever for its own good, there’s some room for a flaw. Bash is what you see as a terminal prompt, but it also is a scripting language, and has the ability to define functions.More at Fedora Magazine
