The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The exact prerequisite is network reachability to the ONVIF device service on a Kiloview E3 NDI encoder running firmware below 1.30; the service accepts hostname, DNS, and NTP configuration write operations without authentication regardless of the device's configured authentication setting for that service, so even devices where ONVIF authentication is enabled remain exploitable. No credentials, user interaction, or non-default configuration is required (PR:N/UI:N/AC:L). The primary limiting factor is network exposure: the device service must be reachable by the attacker, so devices isolated on segmented or firewalled OT/AV networks are not remotely exploitable, and impact is limited to configuration integrity (no direct data disclosure or denial of service), with the most serious consequences being follow-on traffic interception or certificate validation bypass rather than immediate compromise.

Impact

This is a genuine, actionable priority rather than a CVSS-inflated non-issue, but the risk is scoped to integrity manipulation rather than direct compromise. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms a remote, unauthenticated attack with low complexity and no user interaction against the ONVIF device service - the most favorable conditions for an attacker - and the vector correctly scores only integrity impact (VI:H) with no confidentiality (VC:N) or availability (VA:N) effect, matching a CWE-306 missing-authentication flaw that permits configuration writes but not direct data theft or outage. CISA ICS-CERT reporting (icsa-26-295-01) and a vendor patch raise confidence that the flaw is real and vendor-confirmed. No EPSS score was provided and the vulnerability is NOT in CISA KEV, and no public exploit or PoC reference is present in the input, so there is no evidence of active exploitation or widely available weaponized code. The vuln.today decision label is 'this_week', which aligns with a serious-but-not-emergency posture: unauthenticated network write access is dangerous, but the direct impact is configuration tampering that primarily enables follow-on attacks (traffic interception, certificate validation bypass via DNS/NTP manipulation) rather than immediate code execution. The principal uncertainty is exploitation probability: with no EPSS and no KEV, likelihood of real-world attack cannot be quantified from the provided data.

Exploit ScenarioDerived

An attacker with network reachability to a Kiloview E3 encoder sends ONVIF configuration write requests to the device service without any credentials, overriding the device's configured authentication setting. They redirect the device's DNS resolver or NTP time source to attacker-controlled infrastructure, setting up man-in-the-middle traffic interception or certificate validation bypass for the device's subsequent connections. No public exploit code or PoC reference is identified in the available data; exploitation would require crafting ONVIF SOAP requests, which is low-complexity per the CVSS vector.

AnalysisAIv2 – Oct 22, 2026

Remote, unauthenticated attackers can change the hostname, DNS servers, and NTP time source on Kiloview E3 NDI encoder firmware before 1.30 through the ONVIF device service, even when authentication is enabled for that service (CVSS 8.7). The flaw is an authentication bypass for configuration write operations (CWE-306) with high integrity impact but no direct confidentiality or availability impact; exploitation requires network reachability to the ONVIF service. No public exploit identified at time of analysis, and the vendor provides a firmware update.

Earlier versions of this analysis (1)
v1 Oct 22, 2026 - 23:01 CVSS 7.5

The ONVIF device service on Kiloview E3 NDI encoder firmware processes hostname, DNS, and NTP configuration-write requests without authenticating the caller, and this holds even when ONVIF authentication is enabled on the device. A remote, unauthenticated attacker who can reach that service (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N, 7.5) can rewrite the encoder's hostname, repoint DNS resolution, or change its time source, enabling follow-on traffic interception or certificate validation bypass; impact is limited to integrity of those settings plus their downstream effects. No public exploit code was identified at time of analysis, the issue is not in CISA KEV, and vuln.today prioritizes it as 'this_week' - a genuine but bounded priority whose limiting factor is whether the encoder's ONVIF service is reachable from untrusted networks.

RemediationAI

Vendor-released patch: update Kiloview E3 firmware to version 1.30 or later; the vendor firmware download page is https://www.kiloview.com/en/download/e3-firmware-downloadlatest-12/ and the CISA ICS advisory ICSA-26-295-01 provides additional detail. Until the update is applied, restrict network access to the ONVIF device service so only trusted management hosts or AV/OT management VLANs can reach it, and block the service at network boundaries; this reduces exposure but can break legitimate ONVIF discovery and management integrations and must be scoped to the deployment. Because the writes are accepted regardless of the service's authentication setting, enabling ONVIF authentication alone is not a reliable mitigation, and operators should verify hostname, DNS, and NTP settings after exposure.

Technical ContextAI · show details

The affected component is the ONVIF device service in Kiloview E3 NDI encoder firmware, exposed over the network and used for device management and integration with ONVIF clients. CWE-306 (Missing Authentication for Critical Function) applies because the hostname, DNS, and NTP configuration write operations do not enforce authentication, and the omission persists regardless of the device's configured authentication setting for the service. This is a configuration-integrity issue: an attacker who can reach the service can redirect name resolution or change the time source, which can support follow-on interception or certificate-validation bypass; the vulnerability does not by itself provide code execution, data disclosure, or denial of service. CPE data identifies the affected package as cpe:2.3:a:kiloview:e3_firmware:*:*:*:*:*:*:*:*.

DescriptionCVE.org

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.

Executive ViewAI

Why It Matters

The Kiloview E3 NDI encoder, used for video-over-IP workflows, has a high-severity flaw (CVE-2026-110825) allowing remote, unauthenticated attackers to alter critical network settings such as hostname, DNS, and NTP. This integrity compromise could disrupt broadcast operations and enable further network attacks. Leadership should prioritize patching to prevent operational disruption and potential lateral movement.
