CVE-2026-48248

# PoC Concept: Python script demonstrating the vulnerability by ignoring SSL verification # In a real attack scenario, an attacker would use a tool like mitmproxy to intercept traffic. import requests # Target URL (Example endpoint that the application might call) target_url = "https://example.com/api/auth" # Malicious proxy or endpoint setup is assumed by the attacker # The vulnerability allows the client to accept any certificate def vulnerable_request(): try: # This simulates the vulnerable configuration in incs/login.inc.php # verify=False is equivalent to CURLOPT_SSL_VERIFYPEER = false response = requests.get(target_url, verify=False, timeout=5) # If successful, the client accepted a potentially invalid certificate print(f"[+] Connection established to {target_url}") print(f"[+] Response Status: {response.status_code}") print(f"[+] Data leaked (if any): {response.text[:100]}...") print("[!] Vulnerability confirmed: TLS verification is disabled.") except requests.exceptions.SSLError: print("[-] SSL Verification failed (Not Vulnerable)") except Exception as e: print(f"[-] Error: {e}") if __name__ == "__main__": # Suppress InsecureRequestWarning for demonstration purposes requests.packages.urllib3.disable_warnings(requests.packages.urllib3.exceptions.InsecureRequestWarning) vulnerable_request()
