Vulnerability from fkie_nvd - Published: 2025-06-27 15:15 - Updated: 2025-08-21 18:39
Severity ?
9.6 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Summary
authentik is an open-source identity provider. After authorizing access to a RAC endpoint, authentik creates a token which is used for a single connection and is sent to the client in the URL. This token is intended to only be valid for the session of the user who authorized the connection, however this check is missing in versions prior to 2025.6.3 and 2025.4.3. When, for example, using RAC during a screenshare, a malicious user could access the same session by copying the URL from the shown browser. authentik 2025.4.3 and 2025.6.3 fix this issue. As a workaround, it is recommended to decrease the duration a token is valid for (in the RAC Provider settings, set Connection expiry to `minutes=5` for example). The maintainers of authentik also recommend enabling the option Delete authorization on disconnect.

Este token est\u00e1 dise\u00f1ado para ser v\u00e1lido \u00fanicamente durante la sesi\u00f3n del usuario que autoriz\u00f3 la conexi\u00f3n; sin embargo, esta comprobaci\u00f3n no est\u00e1 disponible en versiones anteriores a 2025.6.3 y 2025.4.3. Por ejemplo, al usar RAC durante una pantalla compartida, un usuario malintencionado podr\u00eda acceder a la misma sesi\u00f3n copiando la URL del navegador mostrado. Authentik 2025.4.3 y 2025.6.3 soluciona este problema. Como soluci\u00f3n alternativa, se recomienda reducir la validez de un token (por ejemplo, en la configuraci\u00f3n del proveedor RAC, establezca la caducidad de la conexi\u00f3n en `minutos=5`). Los desarrolladores de Authentik tambi\u00e9n recomiendan habilitar la opci\u00f3n \"Eliminar autorizaci\u00f3n al desconectar\"."
