Description

openhole exposes localhost to the internet in one command. In 0.1.1 and earlier, openhole-server in internal/server/public_proxy.go forwarded r.URL.Path instead of preserving the original request target with r.URL.EscapedPath(), allowing percent encoded dot segments %2e and separators %2f to reach tunneled local services as ../ and / for path traversal. This issue is fixed in version 0.1.2.

• CWE-22Improper 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.
