Detailsinfo

A vulnerability classified as problematic was found in Vite (version now known). This vulnerability affects some unknown processing of the component File System Handler. The manipulation with an unknown input leads to a case sensitivity vulnerability. The CWE definition for the vulnerability is CWE-178. The product does not properly account for differences in case sensitivity when accessing or determining the properties of a resource, leading to inconsistent results. As an impact it is known to affect confidentiality. CVE summarizes:

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 [email protected], [email protected], [email protected], and [email protected]. Users are advised to upgrade. Users unable to upgrade should restrict access to dev servers.
