Warp vulnerable to Path Traversal via Improper validation of Windows paths

High severity GitHub Reviewed Published Jan 31, 2023 to the GitHub Advisory Database • Updated Mar 31, 2023

Package

cargo warp (Rust)

Affected versions

< 0.3.3

Patched versions

0.3.3

Description

Path resolution in warp::filters::fs::dir didn't correctly validate Windows paths meaning paths like /foo/bar/c:/windows/web/screen/img101.png would be allowed and respond with the contents of c:/windows/web/screen/img101.png. Thus users could potentially read files anywhere on the filesystem.

This only impacts Windows. Linux and other unix likes are not impacted by this.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
