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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
