CVE-2024-23331

Vite is a frontend tooling framework for javascript. The Vite dev server option `server.fs.deny` can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows. This bypass is similar to CVE-2023-34092 -- with surface area reduced to hosts having case-insensitive filesystems. Since `picomatch` defaults to case-sensitive glob matching, but the file server doesn't discriminate; a blacklist bypass is possible. By requesting raw filesystem paths using augmented casing, the matcher derived from `config.server.fs.deny` fails to block access to sensitive files. This issue has been addressed in vite@5.0.12, vite@4.5.2, vite@3.2.8, and vite@2.9.17. Users are advised to upgrade. Users unable to upgrade should restrict access to dev servers.

La opci\u00f3n del servidor de desarrollo de Vite `server.fs.deny` se puede omitir en sistemas de archivos que no distinguen entre may\u00fasculas y min\u00fasculas utilizando versiones de nombres de archivos aumentadas entre may\u00fasculas y min\u00fasculas. Cabe destacar que esto afecta a los servidores alojados en Windows.

Dado que `picomatch` por defecto utiliza coincidencias globales que distinguen entre may\u00fasculas y min\u00fasculas, pero el servidor de archivos no discrimina; es posible omitir la lista negra. Al solicitar rutas de sistema de archivos sin formato usando may\u00fasculas aumentadas, el comparador derivado de `config.server.fs.deny` no logra bloquear el acceso a archivos confidenciales. Este problema se ha solucionado en vite@5.0.12, vite@4.5.2, vite@3.2.8 y vite@2.9.17. Se recomienda a los usuarios que actualicen.
