Kiloview E3 NDI Encoder: 9 CVEs, Critical 9.9
Summary
CISA reports 9 vulnerabilities in Kiloview E3 Firmware. Weakness types: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), Missing Authentication for Critical Function, Insufficient Session Expiration (+3 more). Successful exploitation of this these vulnerabilities could allow an attacker to fully compromise the device. Highest CVSS v3 score: 9.9 (Critical), exploitable over the network.
What to do: Act now: KiloView recommends users update to V1.30: https://www.kiloview.com/en/download/e3-firmware-downloadlatest-12/

Vulnerabilities
| CVE | Weakness | CVSS v3 | CVSS v4 | KEV | Description (from advisory) |
|---|---|---|---|---|---|
| CVE-2026-109122 | Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') | 9.1 | – | No | The network management service on affected Kiloview E3 NDI encoder firmware fails to sanitize one field used when configuring static routes via the web management API. An authenticated web user with permission to configure static routes can exploit this to execute arbitrary operating system commands as root, and the malicious configuration persists across reboots. Successful exploitation could res… |
| CVE-2026-111100 | Missing Authentication for Critical Function | 5.3 | – | No | The ONVIF device service on the E3 responds to certain informational requests without requiring authentication. A remote, unauthenticated party can retrieve detailed device identifiers along with a list of configured user accounts and their privilege levels. This aids attackers in fingerprinting vulnerable devices and preparing targeted credential attacks. |
| CVE-2026-96616 | Insufficient Session Expiration | 6.5 | – | No | Authentication tokens issued by the E3's web management interface on login are given an expiration time far beyond any reasonable session lifetime, effectively making them non-expiring. A token obtained through interception or device compromise remains valid for authenticated access for an extended period. |
| CVE-2026-105265 | Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') | 5.3 | – | No | A vulnerability exists in the the time zone parameter and does not properly validate user input, which may allow an authenticated user to cause /etc/localtime to point to a file outside the intended zoneinfo directory |
| CVE-2026-110491 | NULL Pointer Dereference | 7.5 | – | No | The ONVIF service on the E3 can be rendered unresponsive by sending malformed or incomplete requests to certain operations. The affected service stops accepting new connections while the rest of the device continues operating normally, and will recover automatically after a period. This can be triggered repeatedly by any unauthenticated party with network access to the device. |
| CVE-2026-107861 | Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') | 9.9 | – | No | The system control service on affected Kiloview E3 NDI encoder firmware fails to sanitize the hostname parameter accepted by its device naming endpoint, passing it unquoted into a shell command. An authenticated web user with access to this function can embed characters to execute arbitrary operating system commands as root, resulting in full device compromise. |
| CVE-2026-110243 | Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') | 9.9 | – | No | The network management service on affected Kiloview E3 NDI encoder firmware fails to validate the network interface name accepted by its link maintenance address configuration endpoint before passing it to a shell command, unlike sibling handlers that perform the same validation. An authenticated web user with permission to configure network settings can exploit this to execute arbitrary operating… |
| CVE-2026-92450 | Use of Hard-coded Credentials | 7.5 | – | No | The authentication framework used by affected Kiloview E3 NDI encoder firmware signs session JSON Web Tokens using an HMAC-SHA256 secret hardcoded as a static string within the firmware image, identical across all deployed devices. An attacker with access to the publicly distributed firmware can recover this secret and forge arbitrary session tokens, including administrative tokens, without valid … |
| CVE-2026-110825 | Missing Authentication for Critical Function | 7.5 | – | No | 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… |
