Detailsinfo

A vulnerability was found in honojs node-server up to 1.4.0. It has been rated as critical. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality. CVE summarizes:

@hono/node-server is an adapter that allows users to run Hono applications on Node.js. Since v1.3.0, @hono/node-server has used its own Request object with `url` behavior that is unexpected. In the standard API, if the URL contains `..`, here called "double dots", the URL string returned by Request will be in the resolved path. However, the `url` in @hono/node-server's Request as does not resolve double dots, so `http://localhost/static/.. /foo.txt` is returned. This causes vulnerabilities when using `serveStatic`. Modern web browsers and a latest `curl` command resolve double dots on the client side, so this issue doesn't affect those using either of those tools. However, problems may occur if accessed by a client that does not resolve them. Version 1.4.1 includes the change to fix this issue. As a workaround, don't use `serveStatic`.

The weakness was disclosed 01/23/2024 as GHSA-rjq5-w47x-x359. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2024-23340 since 01/15/2024. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 1.4.1 eliminates this vulnerability. Applying the patch dd9b9a9b23e3896403c90a740e7f1f0892feb402 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
