7.3/10

Summary

In the ABB IDAL FTP server, an authenticated attacker can traverse to arbitrary directories on the hard disk with "CWD ../" and then use the FTP server functionality to download and upload 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.
