The core of the exploit lies in how the API handles the ip parameter. In the UltraTech CTF walkthrough , the application is observed using a Node.js Express backend that takes a URL like http://[IP]:8081/ping?ip=[target] and passes the ip value directly to a system shell command (likely a standard ping utility).
Since '1'='1' always evaluates to true, the query returns from the devices table, potentially exposing device credentials, IP addresses, and configuration data. ultratech api v0.1.3 exploit

If shell execution is unavoidable, use functions that take arguments as an array (like spawn in Node.js) to prevent command string concatenation. : At ID 0114 , the script returned
Once command injection is confirmed, the exploit path usually involves escalating from a simple query to a full Remote Code Execution (RCE) Enumeration : Attackers use tools like to find hidden endpoints like Reverse Shell
