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 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 credentials, enabling unauthenticated access to privileged device functions.

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.

An issue in KiloView Dual Channel 4k HDMI & 3G-SDI HEVC Video Encoder Firmware v.1.20.0006 allows a remote attacker to cause a denial of service via the systemctrl API System/reFactory component.

Hardcoded TLS private key and certificate in firmware in Kiloview N30 2.02.246 allows malicious adversary to do a Mann-in-the-middle attack via the network

A broken authorization vulnerability in Kiloview NDI N30 allows a remote unauthenticated attacker to deactivate user verification, giving them access to state changing actions that should only be initiated by administratorsThis issue affects

Kiloview NDI N30

and was fixed in Firmware version later than 2.02.0246

The device is observed to accept deprecated TLS protocols, increasing the risk of cryptographic weaknesses.

The server supports at least one cipher suite which is on the NCSC-NL list of cipher suites to be phased out, increasing the risk of cryptographic weaknesses.

The webserver utilizes basic authentication for its user login to the configuration interface. As encryption is disabled on port 80, it enables potential eavesdropping on user traffic, making it possible to intercept their credentials.

The user management section of the web application permits the creation of user accounts with excessively weak passwords, including single-character passwords.

A 'Cross-site Scripting' (XSS) vulnerability, characterized by improper input neutralization during web page generation, has been discovered. This vulnerability allows for Stored XSS attacks to occur. Multiple areas within the administration interface of the webserver lack adequate input validation, resulting in multiple instances of Stored XSS vulnerabilities.

A vulnerability allows attackers to download source code or an executable from a remote location and execute the code without sufficiently verifying the origin and integrity of the code. This vulnerability can allow attackers to modify the firmware before uploading it to the system, thus achieving the modification of the target’s integrity to achieve an insecure state.

The vulnerability allows attackers access to the root account without having to authenticate. Specifically, if the device is configured with the IP address of 10.10.10.10, the root user is automatically logged in.

Hardcoded credentials are discovered within the application's source code, creating a potential security risk for unauthorized access.

A vulnerability allows unauthorized access to functionality inadequately constrained by ACLs. Attackers may exploit this to unauthenticated execute commands potentially leading to unauthorized data manipulation, access to privileged functions, or even the execution of arbitrary code.

An OS Command Injection vulnerability in Kiloview NDI allows a low-privileged user to execute arbitrary code remotely on the device with high privileges.

This issue affects Kiloview NDI N3, N3-s, N4, N20, N30, N40 and was fixed in Firmware version 2.02.0227 .
