CVE-2024-28179

Estado: AnalizadaCrítica (9.8)—

Jupyter Server Proxy allows users to run arbitrary external processes alongside their Jupyter notebook servers and provides authenticated web access. Prior to versions 3.2.3 and 4.1.1, Jupyter Server Proxy did not check user authentication appropriately when proxying websockets, allowing unauthenticated access to anyone who had network access to the Jupyter server endpoint. This vulnerability can allow unauthenticated remote access to any websocket endpoint set up to be accessible via Jupyter Server Proxy.

Leer descripción completaMostrar menos

In many cases, this leads to remote unauthenticated arbitrary code execution, due to how affected instances use websockets. The websocket endpoints exposed by `jupyter_server` itself is not affected. Projects that do not rely on websockets are also not affected. Versions 3.2.3 and 4.1.1 contain a fix for this issue.

Antes de las versiones 3.2.3 y 4.1.1, Jupyter Server Proxy no verificaba adecuadamente la autenticación del usuario al utilizar websockets, lo que permitía el acceso no autenticado a cualquier persona que tuviera acceso de red al endpoint del servidor Jupyter. Esta vulnerabilidad puede permitir el acceso remoto no autenticado a cualquier endpoint de websocket configurado para ser accesible a través de Jupyter Server Proxy. En muchos casos, esto conduce a la ejecución remota de código arbitrario no autenticado, debido a cómo las instancias afectadas usan websockets. Los endpoints de websocket expuestos por el propio `jupyter_server` no se ven afectados. Los proyectos que no dependen de websockets tampoco se ven afectados. Las versiones 3.2.3 y 4.1.1 contienen una solución para este problema. "
