High
7.2/10

Summary

Triangle MicroWorks SCADA Data Gateway Event Log Directory Traversal Arbitrary File Creation Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of Triangle MicroWorks SCADA Data Gateway. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the creation of event logs. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-20534.

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.
