CVE-2026-110825 in Kiloview
Summary
by MITRE • 10/23/2026
The ONVIF device service on affected Kiloview E3 NDI encoder firmware accepts hostname, DNS, and NTP configuration write operations without requiring authentication, regardless of the device's configured authentication setting for this service. A remote, unauthenticated attacker can alter the device hostname, redirect DNS resolution, or modify the configured time source, enabling follow on attacks such as traffic interception or certificate validation bypass.

The vulnerability identified in Kiloview E3 NDI encoder firmware represents a critical failure in access control mechanisms within the ONVIF device service implementation. Specifically, the system fails to enforce authentication requirements for configuration write operations related to hostname, Domain Name System (DNS), and Network Time Protocol (NTP) settings. This flaw persists regardless of whether the administrator has enabled or disabled general authentication for the ONVIF interface, indicating a hardcoded bypass or misconfiguration in the service logic that treats these specific administrative endpoints as public-facing resources rather than protected management interfaces.
From a technical perspective, this issue stems from an improper enforcement of authorization policies on sensitive configuration parameters. The device accepts HTTP requests to modify network identity and resolution settings without verifying the credentials of the requesting party. This allows any remote actor with network connectivity to the target device to inject arbitrary values into these fields. By altering the hostname, attackers can disrupt local service discovery mechanisms or cause confusion in logging systems that rely on unique identifiers for asset tracking. More critically, the ability to modify DNS settings enables an attacker to redirect traffic intended for legitimate services toward malicious infrastructure under their control.
The operational impact of this vulnerability is severe due to its potential to facilitate broader network compromise and surveillance. By manipulating DNS records, a remote unauthenticated attacker can perform man-in-the-middle attacks against video streams or management interfaces sent by the encoder. This redirection allows for traffic interception, where sensitive data such as live video feeds or administrative credentials transmitted in cleartext can be captured. Furthermore, modifying NTP settings to point to a malicious time server can disrupt certificate validation processes that rely on accurate system time, potentially allowing attackers to exploit expired certificates or bypass security checks that depend on temporal validity windows.
This vulnerability aligns with CWE-284, which describes Improper Access Control, as the application fails to restrict access to critical configuration functions. It also maps directly to MITRE ATT&CK technique T1071, Application Layer Protocol, where adversaries use standard protocols like HTTP or ONVIF for command and control or data exfiltration without triggering typical security alerts due to the lack of authentication requirements. The ability to alter network settings is further categorized under CWE-693, Protection Mechanism Failure, as the device's built-in safeguards are rendered ineffective against unauthenticated requests.
Mitigation strategies should prioritize immediate patching if a firmware update addressing this access control flaw is available from Kiloview. In environments where updates cannot be applied immediately, network segmentation is essential to restrict ONVIF service ports to trusted management subnets only. Administrators should also implement strict firewall rules that block external or untrusted IP addresses from accessing the device's configuration endpoints. Additionally, enabling HTTPS for all administrative interfaces and ensuring certificate validation is robust against time manipulation can reduce the risk of successful exploitation even if DNS settings are compromised. Regular auditing of ONVIF service configurations to ensure authentication is enforced on all write operations is also recommended to prevent similar misconfigurations in other devices within the network infrastructure.
