What is “Bash Bug”?

The Shellshock vulnerabilities affect Bash, a program that various Unix-based systems use to execute command lines and command scripts. It is often installed as the system’s default command-line interface.

Shellshock, also known as Bashdoor, is a family of security bugs in the widely used Unix Bash shell, the first of which was disclosed on September 24, 2014. Many Internet daemons, such as web servers, use Bash to process certain commands, allowing an attacker to cause vulnerable versions of Bash to execute arbitrary commands. This can allow an attacker to gain unauthorized access to a computer system.

What to do next?

In addition to patching / updating your endpoints and/or infrastructure, there are workarounds for specific products and services outlined by the manufacturers.  For instance, Cisco C series, EX series, MX series, MXG2 series, SX series can be protected by disabling DHCP and SSH.
