There is an uncontrolled search path element (DLL Hijacking) vulnerability. To exploit this vulnerability, an attacker could rename a malicious DLL to meet the criteria of the application, and the application would not verify that the DLL is correct.

The attacker would need to have administrative access to the default install location in order to plant the insecure DLL. Once loaded by the application, the DLL could run malicious code at the privilege level of the application.

CVE-2017-5170 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.2.

The product sees action in the critical manufacturing, energy, and transportation systems sectors. It also sees use on a global basis.

Taiwan-based Moxa provided software update Version 3.4 for SoftNVR-IA Live Viewer which fixes this vulnerability.
