NVMS Configuration API security vulnerability

Summary

When the NVMS Configuration API is used to modify security settings, it fails to perform the necessary security checks. There are hotfixes available for versions 2016-R3 through 2017-R2.

Symptoms

  1. Missing authorization validation when changing device properties (Version 2016-R3 and 2017-R2)

  2. Incorrect authorization validation when changing role security (Version 2017-R2)

Cause

We have identified three related vulnerabilities in the NVMS Configuration API that can cause an elevation of privileges and affect the Management Server's security if exploited in Network Video Management System Enterprise Edition.
