Detailsinfo

A vulnerability was found in parisneo lollms-webui up to 9.1. It has been classified as problematic. This affects an unknown function. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. The summary by CVE is:

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 blocked when in headless mode for obvious security reasons!"} if lollmsElfServer.config.host=="0.0.0.0": return {"status":False,"error":"Code execution is blocked when the server is exposed outside for very obvipous reasons!"} try: data = (await request.json()) code = data["code"] discussion_id = int(data.get("discussion_id","unknown_discussion")) message_id = int(data.get("message_id","unknown_message")) language = data.get("language","python") if language=="python": ASCIIColors.info("Executing python code:") ASCIIColors.yellow(code) return execute_python(code, discussion_id, message_id) if language=="javascript": ASCIIColors.info("Executing javascript code:") ASCIIColors.yellow(code) return execute_javascript(code, discussion_id, message_id) if language in ["html","html5","svg"]: ASCIIColors.info("Executing javascript code:") ASCIIColors.yellow(code) return execute_html(code, discussion_id, message_id) elif language=="latex": ASCIIColors.info("Executing latex code:") ASCIIColors.yellow(code) return execute_latex(code, discussion_id, message_id) elif language in ["bash","shell","cmd","powershell"]: ASCIIColors.info("Executing shell code:") ASCIIColors.yellow(code) return execute_bash(code, discussion_id, message_id) elif language in ["mermaid"]: ASCIIColors.info("Executing mermaid code:") ASCIIColors.yellow(code) return execute_mermaid(code, discussion_id, message_id) elif language in ["graphviz","dot"]: ASCIIColors.info("Executing graphviz code:") ASCIIColors.yellow(code) return execute_graphviz(code, discussion_id, message_id) return {"status": False, "error": "Unsupported language", "execution_time": 0} except Exception as ex: trace_exception(ex) lollmsElfServer.error(ex) return {"status":False,"error":str(ex)} ``` I also added an optional https mode and looking forward to add a full authentication with cookies and a personal session etc. All updates will be in V 9.1 Again, thanks alot for your work. I will make it harder next time, but if you find more bugs, just be my guest :)
