CVE-2022-39215 – The readDir Endpoint Scope can be Bypassed With Symbolic Links in Tauri

https://notcve.org/view.php?id=CVE-2022-39215

Tauri is a framework for building binaries for all major desktop platforms. Due to missing canonicalization when `readDir` is called recursively, it was possible to display directory listings outside of the defined `fs` scope. This required a crafted symbolic link or junction folder inside an allowed path of the `fs` scope. No arbitrary file content could be leaked. The issue has been resolved in version 1.0.6 and the implementation now properly checks if the requested (sub) directory is a symbolic link outside of the defined `scope`. • https://github.com/tauri-apps/tauri/issues/4882 https://github.com/tauri-apps/tauri/pull/5123 https://github.com/tauri-apps/tauri/pull/5123/commits/1f9b9e8d26a2c915390323e161020bcb36d44678 https://github.com/tauri-apps/tauri/security/advisories/GHSA-28m8-9j7v-x499 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
