Descriptions

A path traversal vulnerability exists in the `_create_model_version()` function within `server/handlers.py` of the mlflow/mlflow repository, due to improper validation of the `source` parameter. Attackers can exploit this vulnerability by crafting a `source` parameter that bypasses the `_validate_non_local_source_contains_relative_paths(source)` function's checks, allowing for arbitrary file read access on the server. The issue arises from the handling of unquoted URL characters and the subsequent misuse of the original `source` value for model version creation, leading to the exposure of sensitive files when interacting with the `/model-versions/get-artifact` handler.

Existe una vulnerabilidad de path traversal en la función `_create_model_version()` dentro de `server/handlers.py` del repositorio mlflow/mlflow, debido a una validación incorrecta del parámetro `source`. Los atacantes pueden explotar esta vulnerabilidad creando un parámetro `source` que pasa por alto las comprobaciones de la función `_validate_non_local_source_contains_relative_paths(source)`, permitiendo acceso de lectura arbitrario a archivos en el servidor. El problema surge del manejo de caracteres URL sin comillas y el posterior uso indebido del valor "fuente" original para la creación de la versión del modelo, lo que lleva a la exposición de archivos confidenciales al interactuar con el controlador "/model-versions/get-artifact".
