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.

Kiloview E3 NDI encoder firmware versions prior to 1.30 contain a vulnerability where the authentication framework uses a hardcoded HMAC-SHA256 secret to sign session JSON Web Tokens. This secret is identical across all devices and can be extracted from the publicly available firmware. An attacker can use this secret to forge session tokens, including administrative tokens, allowing unauthenticated access to privileged functions on the device.

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 system commands as root.

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.

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.

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 .

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.

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.

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 result in full device compromise, including exposure of stored credentials and cryptographic material.

A missing authentication for critical function vulnerability in KiloView Encoder Series could allow an unauthenticated attacker to create or delete administrator accounts. This vulnerability can grant the attacker full administrative control over the product.
