Vulnerability from variot

Delta Industrial Automation DIALink versions prior to v1.5.0.0 Beta 4 uses an external input to construct a pathname intended to identify a file or directory located underneath a restricted parent directory. However, the software does not properly neutralize special elements within the pathname, which can cause the pathname to resolve to a location outside of the restricted directory. This vulnerability allows remote attackers to create arbitrary files on affected installations of Delta Industrial Automation DIALink. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.The specific flaw exists within the opcua endpoint of the web service, which listens on TCP port 5000 by default. When parsing the filename parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create files in the context of the web service. Delta Electronics Industrial Automation DIALink is an industrial automation IoT device from Delta Electronics, Taiwan, China
