Exploitation Conditions

JetKVM versions prior to 0.5.4 performing firmware updates over unencrypted or improperly authenticated channels. Attacker must be positioned as man-in-the-middle or control update server.

Impact

CVSS score of 4.7 (MEDIUM).

Exploit ScenarioDerived

An attacker on the network intercepts JetKVM's firmware update request, modifies the firmware binary and its SHA256 hash simultaneously, then serves the malicious package. The device verifies only the hash against the modified version, accepting the compromised firmware.

This Week Schedule remediation this week. Why: HIGH severity (CVSS 7.0-8.9).

AnalysisAIv1 – Mar 17, 2026

JetKVM versions prior to 0.5.4 lack cryptographic verification of firmware update authenticity, allowing attackers positioned on the network or controlling the update server to inject malicious firmware that bypasses hash validation. This enables local attackers with user interaction to compromise system integrity through a man-in-the-middle attack or server compromise. A patch is available to address this vulnerability.
