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

CVE-2024-3429

High
9.8/10

Summary

A path traversal vulnerability exists in the parisneo/lollms application versions 9.3.0 prior to 9.5.0, specifically within the "sanitize_path_from_endpoint" and "sanitize_path" functions in "lollms_core\lollms\security.py". This vulnerability allows for arbitrary file reading when the application runs on Windows. The issue arises due to insufficient sanitization of user-supplied input, enabling attackers to bypass the path traversal protection mechanisms by crafting malicious input. Successful exploitation could lead to unauthorized access to sensitive files, information disclosure, and potentially a Denial of Service (DoS) condition by including numerous large or resource-intensive files.

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.
