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

CVE-2023-23608

Medium
4.3/10

Summary

Spotipy is a lightweight Python library for the Spotify Web API. In versions prior to 2.22.1, if a malicious URI is passed to the library, the library can be tricked into performing an operation on a different API endpoint than intended. The code Spotipy uses to parse URIs and URLs allows an attacker to insert arbitrary characters into the path that is used for API requests. Because it is possible to include "..", an attacker can redirect for example a track lookup via "spotifyApi.track()" to an arbitrary API endpoint like playlists, but this is possible for other endpoints as well. The impact of this vulnerability depends heavily on what operations a client application performs when it handles a URI from a user and how it uses the responses it receives from the API.

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.
