Is this vulnerability remotely exploitable?

Yes, it can be remotely exploitable if the ONVIF interface is reachable over the network. An attacker who can send crafted SOAP GetStreamUri requests to the camera may be able to trigger the overflow.

Does an attacker need authentication to exploit this issue?

That depends on how the ONVIF service is configured. If GetStreamUri can be invoked without authentication or with easily guessable credentials, the barrier to exploitation is low. Even when authentication is required, compromised or shared credentials could enable an attacker to reach the vulnerable code path.

What is the safest general fix pattern for this vulnerability?

The most robust fix is to implement strict bounds checking for all copies into fixed-size buffers and to use safe string and buffer APIs that require maximum lengths. Any field, such as Protocol, should be validated against a defined maximum length and rejected if it exceeds that limit.
