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

CVE-2022-39812

Severity High
Score 7.5/10

Summary

Italtel NetMatch-S CI 5.2.0-20211008 allows Absolute Path Traversal under NMSCI-WebGui/SaveFileUploader. An unauthenticated user can upload files to an arbitrary path. An attacker can change the uploadDir parameter in a POST request (not possible using the GUI) to an arbitrary directory. Because the application does not check in which directory a file will be uploaded, an attacker can perform a variety of attacks that can result in unauthorized access to the server.

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.
