Is this vulnerability remotely exploitable over the internet?

It can be, if the DVRIP service on TCP port 34567 is exposed to the internet and an attacker can obtain valid credentials (e.g., via weak passwords, reuse, or other compromise). In many deployments the risk also exists from internal or adjacent networks.

Does an attacker need valid authentication to exploit this?

Yes, exploitation as described requires authenticated access to the DVRIP protocol to invoke the NetWork.NetCommon configuration handler. However, weak or default credentials significantly lower the barrier for attackers.

What is the safest general fix pattern for developers and vendors?

The most robust fix is to eliminate shell-based configuration updates: replace `system()` and similar calls with direct API or library calls, and enforce strict allowlists on all configuration values such as HostName so that only expected characters and lengths are accepted.
