If you use web applications that are developed with Linux, then you've probably heard of the Bash Shellshock vulnerability. The security bug allows the possibility of an attacker to gain access to your system in order to execute commands from environment variables. The Bash vulnerability made it to the headlines in 2017, a few months after the heartbleed vulnerability was announced.

The Bash Shellshock vulnerability was discovered by Stephane Chazelas and assigned to the CVE identifier cve–2014–6271. An analogous bug with similar characteristics was discovered by Tavis Ormandy and given the CVE identifier cve-2014-7169.

The Bash Shellshock Bug Can Introduce Risks to Your Web Environment

Unfortunately, the Bash Shellshock bug vulnerability is not limited to Linux environments; it can affect versions of UNIX and Mac OS X as well. Through the Shellshock bug an attacker can send commands to your server through a HTTP request which will then be executed by the Web server's operating system. If your system is compromised, not only can the Shellshock bug allow a hacker to run unintended code remotely, it could also allow one of these outside agents to gain access permission to one web server or even to dive deeper into other network computers where your data could be compromised on a bigger scale.
