CVE-2024-47084

Estado: AnalizadaMedia (6.9)—

Gradio is an open-source Python package designed for quick prototyping. This vulnerability is related to **CORS origin validation**, where the Gradio server fails to validate the request origin when a cookie is present. This allows an attacker’s website to make unauthorized requests to a local Gradio server. Potentially, attackers can upload files, steal authentication tokens, and access user data if the victim visits a malicious website while logged into Gradio. This impacts users who have deployed Gradio locally and use basic authentication.

Users are advised to upgrade to `gradio>4.44` to address this issue. As a workaround, users can manually enforce stricter CORS origin validation by modifying the `CustomCORSMiddleware` class in their local Gradio server code. Specifically, they can bypass the condition that skips CORS validation for requests containing cookies to prevent potential exploitation.

      "value": "Gradio es un paquete Python de código abierto diseñado para la creación rápida de prototipos. Esta vulnerabilidad está relacionada con la **validación de origen CORS**, donde el servidor Gradio no puede validar el origen de la solicitud cuando hay una cookie presente. Esto permite que el sitio web de un atacante realice solicitudes no autorizadas a un servidor Gradio local. Potencialmente, los atacantes pueden cargar archivos, robar tokens de autenticación y acceder a los datos del usuario si la víctima visita un sitio web malicioso mientras está conectado a Gradio. Esto afecta a los usuarios que han implementado Gradio localmente y usan autenticación básica. Se recomienda a los usuarios que actualicen a `gradio&gt;4.44` para solucionar este problema. Como workaround, los usuarios pueden aplicar manualmente una validación de origen CORS más estricta modificando la clase `CustomCORSMiddleware` en su código de servidor Gradio local. Específicamente, pueden omitir la condición que omite la validación CORS para las solicitudes que contienen cookies para evitar una posible explotación."
