Shellshock, also known as Bashdoor, is a family of security vulnerabilities in the widely used Unix Bash shell. 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. VTScada does not utilize the Bash shell and is therefore not vulnerable to this exploit.
