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

CVE-2024-7034

High
7.2/10

Summary

In open-webui, the endpoint "/models/upload" is vulnerable to arbitrary file write due to improper handling of user-supplied filenames. The vulnerability arises from the usage of "file_path = f"{UPLOAD_DIR}/{file.filename}"" without proper input validation or sanitization. An attacker can exploit this by manipulating the "file.filename" parameter to include directory traversal sequences, causing the resulting "file_path" to escape the intended "UPLOAD_DIR" and potentially overwrite arbitrary files on the system. This can lead to unauthorized modifications of system binaries, configuration files, or sensitive data, potentially enabling remote command execution.

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.
