Versions prior to 1.0.16 expose a POST `/engines/_configure` endpoint that accepts arbitrary runtime flags without authentication. These flags are passed directly to the underlying inference server (llama.cpp). By injecting the --log-file flag, an attacker with network access to the Model Runner API can write or overwrite arbitrary files accessible to the Model Runner process. When bundled with Docker Desktop (where Model Runner is enabled by default since version 4.46.0), it is reachable from any default container at model-runner.docker.internal without authentication. In this context, the file overwrite can target the Docker Desktop VM disk (`Docker.raw` ), resulting in the destruction of all containers, images, volumes, and build history. However, in specific configurations and with user interaction, it is possible to convert this vulnerability in a container escape. The issue is fixed in Docker Model Runner 1.0.16. Docker Desktop users should update to 4.61.0 or later, which includes the fixed Model Runner. A workaround is available. For Docker Desktop users, enabling Enhanced Container Isolation (ECI) blocks container access to Model Runner, preventing exploitation. However, if the Docker Model Runner is exposed to localhost over TCP in specific configurations, the vulnerability is still exploitable."}, {"lang": "es", "value": "Docker Model Runner (DMR) es un software utilizado para gestionar, ejecutar e implementar modelos de IA usando Docker.

Estos flags se pasan directamente al servidor de inferencia subyacente (llama.cpp). Al inyectar el flag --log-file, un atacante con acceso de red a la API de Model Runner puede escribir o sobrescribir archivos arbitrarios accesibles para el proceso de Model Runner. Cuando se incluye con Docker Desktop (donde Model Runner est\u00e1 habilitado por defecto desde la versi\u00f3n 4.46.0), es accesible desde cualquier contenedor predeterminado en model-runner.docker.internal sin autenticaci\u00f3n. En este contexto, la sobrescritura de archivos puede apuntar al disco de la VM de Docker Desktop ('Docker.raw'), lo que resulta en la destrucci\u00f3n de todos los contenedores, im\u00e1genes, vol\u00famenes e historial de compilaci\u00f3n.
