CVE-2025-9265 is a critical security vulnerability identified in the Kiloview NDI N30 device, a network device interface product widely used in video streaming and broadcasting environments. The vulnerability is classified under CWE-346 (Origin Validation Error), CWE-290 (Authentication Bypass), and CWE-287 (Improper Authentication). It allows a remote attacker with no authentication or user interaction to bypass user verification controls by exploiting a broken authorization mechanism. Specifically, the attacker can deactivate user verification, which is intended to restrict state-changing actions to authorized administrators only. This flaw arises due to insufficient validation of the origin of requests, enabling attackers to send crafted requests that the device erroneously accepts as legitimate administrative commands. The vulnerability affects firmware versions up to and including 2.02.0246 and was addressed in subsequent firmware releases. The CVSS v4.0 base score is 10.0, indicating a critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. Although no active exploits have been reported in the wild, the ease of exploitation and potential for complete device compromise make this a significant threat. The Kiloview NDI N30 is commonly deployed in professional media production and broadcasting environments, where unauthorized control could disrupt operations or lead to data manipulation. The vulnerability's root cause is a failure to properly validate the origin of administrative requests, allowing attackers to bypass authentication and authorization controls.

For European organizations, especially those in media, broadcasting, and professional video streaming sectors, this vulnerability poses a severe risk. Exploitation could allow attackers to gain unauthorized administrative control over Kiloview NDI N30 devices, potentially leading to manipulation or disruption of video streams, unauthorized configuration changes, or denial of service. This could result in operational downtime, reputational damage, and loss of sensitive broadcast content. Given the critical nature of the vulnerability and the lack of required authentication, attackers could easily target exposed devices over the network. The impact extends beyond individual devices to potentially affect entire broadcast workflows and network segments if not contained. Additionally, organizations subject to strict regulatory requirements around data integrity and availability (such as GDPR compliance for data protection) could face compliance risks if the vulnerability is exploited. The absence of known exploits in the wild provides a window for proactive mitigation, but the critical severity demands urgent attention.

1. Immediate firmware upgrade: Organizations should verify the firmware version of all Kiloview NDI N30 devices and upgrade to versions later than 2.02.0246 where the vulnerability is patched. 2. Network segmentation: Isolate Kiloview NDI devices on dedicated network segments with strict access controls to limit exposure to untrusted networks and reduce attack surface. 3. Access control: Implement firewall rules to restrict inbound management traffic to trusted IP addresses only. 4. Monitoring and logging: Enable detailed logging on Kiloview devices and network infrastructure to detect anomalous administrative requests or unauthorized access attempts. 5. Disable unnecessary services: Turn off any unused remote management or network services on the devices to minimize potential attack vectors. 6. Incident response readiness: Prepare incident response plans specific to broadcast infrastructure compromise, including device isolation and forensic analysis procedures. 7. Vendor coordination: Maintain communication with Kiloview for updates, advisories, and additional patches or mitigations. 8. Regular vulnerability assessments: Conduct periodic security assessments of broadcast and streaming infrastructure to identify and remediate similar vulnerabilities proactively.
