Executive Summary

JetKVM versions prior to 0.5.4 do not verify the authenticity of downloaded firmware files. This means that an attacker positioned between the user and the update server (man-in-the-middle) or a compromised update server could alter the firmware and the associated SHA256 hash to bypass verification checks.

Impact Analysis

This vulnerability can allow an attacker to install malicious firmware by modifying the firmware and its verification hash. This could lead to unauthorized code execution or control over the affected device, potentially compromising its integrity and security.
