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

CVE-2024-49366

High
7.7/10

Summary

Nginx UI, a web user interface for the Nginx web server, contains a vulnerability in the package github.com/0xjacky/nginx-ui/api/settings versions v2.0.0-beta.6-patch through v2.0.0-beta.35. The issue arises because the application retrieves the value from the "json" field without proper verification, allowing it to construct a value such as "../../". This can result in arbitrary file writes to the server, potentially leading to a loss of permissions. Users are advised to update to a fixed version to address this vulnerability.

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.
