What is a security issue with CGI?
The security risk with the CGI programs is that they can intentionally or unintentionally leak out confidential information to the attacker. In addition, an attacker can also modify the user input for CGI scripts in a way such that the CGI script will execute harmful commands on the server (Presis, n.d.).
What is CGI Bash?

Basic user input vulnerabilities. One big source of security problems in Perl scripts is improperly validated (or unvalidated) user input. Any time your program might take input from an untrusted user, even indirectly, you should be cautious.
Can a programming language be a security risk?
A programming language, by design, does not normally constitute a security risk; it is with the programmer that the risk is introduced.
