CVE-2026-110243 in Kiloview
Summary
by MITRE • 10/23/2026
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 vulnerability identified in Kiloview E3 NDI encoder firmware represents a critical security flaw rooted in improper input validation within the device's network management service. Specifically, the endpoint responsible for configuring link maintenance addresses fails to sanitize or validate the network interface name provided by the user before utilizing it in subsequent operations. This oversight stands in stark contrast to other handlers within the same system that correctly implement such validations, indicating an inconsistency in security implementation across different functional modules of the firmware. The absence of rigorous checks allows malicious actors to inject shell metacharacters into the input field, which are then passed directly to a command-line interpreter without restriction.
From a technical perspective, this flaw constitutes a classic Command Injection vulnerability, often categorized under CWE-78 in the Common Weakness Enumeration standard. By exploiting the lack of validation on the network interface name parameter, an attacker can manipulate the underlying shell commands executed by the system. Since the vulnerable service typically operates with elevated privileges to manage network configurations, successful exploitation results in the execution of arbitrary operating system commands with root-level permissions. This grants the attacker complete control over the affected device, enabling them to read sensitive data, modify system files, install backdoors, or pivot into other parts of the internal network.
The operational impact of this vulnerability is severe due to the authentication requirements and privilege level involved. While an authenticated web user with specific permissions to configure network settings is required to trigger the exploit, such access is often granted to administrators or authorized technicians during routine maintenance. Once exploited, the attacker gains full root access, which compromises the integrity, confidentiality, and availability of the device. In a professional video production environment where NDI encoders are critical infrastructure for transmitting high-quality video over IP networks, compromising these devices can lead to service disruption, unauthorized surveillance through connected cameras or displays, and potential lateral movement across the network if the encoder is used as a foothold for further attacks.
This vulnerability aligns with several tactics in the MITRE ATT&CK framework, particularly those related to Execution and Privilege Escalation. The initial exploitation phase corresponds to command injection techniques that allow attackers to execute arbitrary code on remote systems. Following successful execution, the attainment of root privileges facilitates privilege escalation, allowing the attacker to bypass standard security restrictions and perform actions with the highest level of system authority. This combination makes the vulnerability particularly dangerous as it not only allows for immediate control but also establishes a persistent presence within the device's operating environment.
Mitigation strategies should focus on both immediate remediation and long-term architectural improvements. The most effective solution is to apply firmware updates provided by Kiloview that address this specific input validation gap, ensuring that all network interface names are strictly validated against an allowlist of known valid interfaces before being passed to shell commands. In cases where patching is not immediately feasible, administrators should restrict access to the web management interface using strong authentication mechanisms and network segmentation policies, limiting exposure to trusted IP addresses only. Additionally, implementing input sanitization techniques that escape or remove special characters from user-supplied data can prevent command injection attempts at the application layer. Regular security audits and code reviews are recommended to identify similar inconsistencies in other handlers across the firmware ecosystem, ensuring a consistent and robust security posture throughout all network management functions.
