GSD-2024-1561
Vulnerability from gsd - Updated: 2024-02-16 06:02Details
An issue was discovered in gradio-app/gradio, where the `/component_server` endpoint improperly allows the invocation of any method on a `Component` class with attacker-controlled arguments. Specifically, by exploiting the `move_resource_to_block_cache()` method of the `Block` class, an attacker can copy any file on the filesystem to a temporary directory and subsequently retrieve it. This vulnerability enables unauthorized local file read access, posing a significant risk especially when the application is exposed to the internet via `launch(share=True)`, thereby allowing remote attackers to read files on the host machine. Furthermore, gradio apps hosted on `huggingface.co` are also affected, potentially leading to the exposure of sensitive information such as API keys and credentials stored in environment variables.

Espec\u00edficamente, al explotar el m\u00e9todo `move_resource_to_block_cache()` de la clase `Block`, un atacante puede copiar cualquier archivo en el sistema de archivos a un directorio temporal y posteriormente recuperarlo. Esta vulnerabilidad permite el acceso de lectura de archivos locales no autorizados, lo que representa un riesgo significativo, especialmente cuando la aplicaci\u00f3n est\u00e1 expuesta a Internet a trav\u00e9s de \"launch(share=True)\", lo que permite a atacantes remotos leer archivos en la m\u00e1quina host. Adem\u00e1s, las aplicaciones de gradio alojadas en `huggingface.co` tambi\u00e9n se ven afectadas, lo que podr\u00eda provocar la exposici\u00f3n de informaci\u00f3n confidencial, como claves API y credenciales almacenadas en variables de entorno."
