FKIE_CVE-2024-1561

Vulnerability from fkie_nvd - Published: 2024-04-16 00:15 - Updated: 2025-07-30 14:48
Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
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.
