A Cross-Site Request Forgery (CSRF) vulnerability in the parisneo/lollms-webui project allows remote attackers to execute arbitrary code on a victim's system. The vulnerability stems from the `/execute_code` API endpoint, which does not properly validate requests, enabling an attacker to craft a malicious webpage that, when visited by a victim, submits a form to the victim's local lollms-webui instance to execute arbitrary OS commands. This issue allows attackers to take full control of the victim's system without requiring direct network access to the vulnerable application.

I have activated the CORS because I had a development ui that uses another port number then I forgot to remove it.

So what I just did is : - First removed the cors configuration that allows everyone to access it : before: ```python sio = socketio.AsyncServer(async_mode="asgi", cors_allowed_origins="*", ping_timeout=1200, ping_interval=30) # Enable CORS for every one ``` after: ```python cert_file_path = lollms_paths.personal_certificates/"cert.pem" key_file_path = lollms_paths.personal_certificates/"key.pem" if os.path.exists(cert_file_path) and os.path.exists(key_file_path): is_https = True else: is_https = False

# Create a Socket.IO server sio = socketio.AsyncServer(async_mode="asgi", cors_allowed_origins=config.allowed_origins+[f"https://localhost:{config['port']}" if is_https else f"http://localhost:{config['port']}"], ping_timeout=1200, ping_interval=30) # Enable CORS for selected origins ```

- Second, I have updated lollms to have two modes (a headless mode and a ui mode). And updated the /execute_code to block if the server is headless or is exposed ```python @router.post("/execute_code") async def execute_code(request: Request): """ Executes Python code and returns the output.

:param request: The HTTP request object. :return: A JSON response with the status of the operation. """ if lollmsElfServer.config.headless_server_mode: return {"status":False,"error":"Code execution is blo…
