Verify usage and assess exposure to the technology.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by accessing the device over the network without needing any prior authentication or special privileges. Once access is gained, they can manipulate the device's authorization system to disable user verification. This allows them to perform administrative actions that would normally be restricted, potentially leading to unauthorized control over the device's functions.

Frequently asked questions

What is the Kiloview NDI N30?

The Kiloview NDI N30 is a network-connected hardware device used for video encoding and decoding. It is commonly deployed in professional production environments to enable high-quality video streaming and remote management of video signals over an IP network.

How does CVE-2025-9265 work?

This vulnerability involves broken authorization, specifically categorized under weakness classes like Improper Authentication (CWE-287) and Authentication Bypass. It allows an attacker to disable user verification, effectively tricking the device into granting administrative access to someone who has not provided valid credentials.

When does this vulnerability trigger?

The flaw triggers when an unauthorized user accesses the device's management interface over a network. Importantly, the vulnerability does not require the attacker to have any existing account or prior privileges; it is not triggered by normal administrative operations conducted through authorized, secure sessions.

Is my device at risk based on Halo Surface Signal?

Halo Surface Signal indicates the risk is higher for devices deployed where the web management interface or streaming endpoints are network-reachable. If your N30 is exposed to the broader network or the internet to facilitate remote production workflows, it is in a position where an attacker could more easily reach the interface.

Do I need to update my Kiloview NDI N30?

Yes, if you use this device, you should assess your inventory and prioritize an update. Firmware versions later than 2.02.0246 address this issue. Start by identifying which devices are in use and evaluating their network connectivity to plan a controlled update process.
