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

CVE-2023-34238

Medium
5.3/10

Summary

Gatsby is a free and open source framework based on React. The Gatsby framework versions through 4.25.6, 5.0.0-alpha-v5.16 through 5.9.0-lmdb-remapchunks.41, 5.10.0-next.0 through gatsby-5.10.0-next.4 contain a Local File Inclusion vulnerability in the `__file-code-frame` and `__original-stack-frame` paths, exposed when running the Gatsby develop server (`gatsby develop`). Any file in scope of the development server could potentially be exposed. It should be noted that by default `gatsby develop` is only accessible via the localhost `127.0.0.1`, and one would need to intentionally expose the server to other interfaces to exploit this vulnerability by using server options such as `--host 0.0.0.0`, `-H 0.0.0.0`, or the `GATSBY_HOST=0.0.0.0` environment variable. Users are advised to upgrade. Users unable to upgrade should avoid exposing their development server to the internet.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
