⚡ CGI Command Injection — Remote Code Execution

This is a simulation of a vulnerable Apache CGI setup where reset.cgi passes the db_prefix parameter directly to a shell command without sanitization. Using URL-encoded %26 (&), attackers can inject arbitrary shell commands.

🔓 How CGI Command Injection Works

When a CGI script passes user-controlled input (like db_prefix) directly into a shell command without sanitization, an attacker can inject shell metacharacters to execute arbitrary commands.

The key is URL encoding:
%26 is the URL-encoded form of &. In a shell context, & is a command separator — like typing cmd1 & cmd2.

Example breakdown:
GET /cgi-bin/dmt/reset.cgi?db_prefix=%26id%26
→ Shell executes: mysqladmin ... db_prefix=&id&
→ The &id& breaks out and runs the id command!
