Vulnerability
This vulnerability occurs because the application injects an attacker-controlled parameter into a system function.
Exploit
To exploit this vulnerability, we just need to send the malicious command we want the server to execute through the projuniqid parameter using the $() syntax.
Thus, we will only have to execute the command nc -lvp 3000 on the attacker's malicious server to receive the reverse shell from the victim server.
