Vulnerability from fkie_nvd - Published: 2026-08-06 22:17 - Updated: 2026-10-24 16:10
Severity
8.6 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N
Summary
Ground Station prior to 0.6.0 contains an unauthenticated blind server-side request forgery vulnerability in the orbital-source configuration path that allows any unauthenticated Socket.IO client to cause the ground-station process to issue outbound HTTP requests to attacker-chosen destinations. Attackers can connect to the Socket.IO server on port 7000 without credentials due to disabled authentication enforcement and a wildcard CORS policy, then submit a data_submission event with submit-orbital-sources action to persist an attacker-supplied URL in the database, then trigger an orbital sync via the equally unauthenticated background_task:start event. The URL is stored with no scheme allowlist, no host validation, and no rejection of loopback, RFC1918, or link-local (cloud instance metadata at 169.254.169.254) addresses, and is passed directly to requests.get in _fetch_http_3le and _fetch_http_omm in backend/tlesync/source_adapters.py. HTTP status codes and error messages from the outbound request are emitted in the orbital_sync_state Socket.IO event to all connected clients, providing a serviceable oracle for interpreting internal-service and cloud-metadata responses even though the raw response body is not directly leaked. Because the malicious source persists in the database across restarts and re-fires every 24 hours on the scheduled sync cycle, the primitive gives durable long-term SSRF without the attacker needing to remain connected.

      "value": "Ground Station anterior a 0.6.0 contiene una vulnerabilidad de falsificaci\u00f3n de petici\u00f3n del lado del servidor ciega no autenticada en la ruta de configuraci\u00f3n de la fuente orbital que permite a cualquier cliente Socket.IO no autenticado causar que el proceso de la estaci\u00f3n terrestre emita peticiones HTTP salientes a destinos elegidos por el atacante. Los atacantes pueden conectarse al servidor Socket.IO en el puerto 7000 sin credenciales debido a la aplicaci\u00f3n de autenticaci\u00f3n deshabilitada y una pol\u00edtica CORS de comod\u00edn, luego enviar un evento data_submission con la acci\u00f3n submit-orbital-sources para persistir una URL proporcionada por el atacante en la base de datos, luego activar una sincronizaci\u00f3n orbital a trav\u00e9s del evento background_task:start, igualmente no autenticado. La URL se almacena sin lista blanca de esquemas, sin validaci\u00f3n de host y sin rechazo de direcciones de bucle invertido, RFC1918 o de enlace local (metadatos de instancia en la nube en 169.254.169.254), y se pasa directamente a requests.get en _fetch_http_3le y _fetch_http_omm en backend/tlesync/source_adapters.py. Los c\u00f3digos de estado HTTP y los mensajes de error de la petici\u00f3n saliente se emiten en el evento Socket.IO orbital_sync_state a todos los clientes conectados, proporcionando un or\u00e1culo \u00fatil para interpretar las respuestas de servicios internos y metadatos de la nube aunque el cuerpo de la respuesta sin procesar no se filtra directamente. Debido a que la fuente maliciosa persiste en la base de datos a trav\u00e9s de los reinicios y se vuelve a activar cada 24 horas en el ciclo de sincronizaci\u00f3n programado, la primitiva proporciona SSRF duradero a largo plazo sin que el atacante necesite permanecer conectado."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
