CVE-2026-32294

Estado: AnalizadaAlta (7)—

JetKVM prior to 0.5.4 does not verify the authenticity of downloaded firmware files. An attacker-in-the-middle or a compromised update server could modify the firmware and the corresponding SHA256 hash to pass verification.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de cadena de suministro en firmware: servidor de actualización comprometido o MITM modifica firmware y hash SHA256, permitiendo inyectar código malicioso sin verificación criptográfica (CWE-345, CWE-347). AV:L/UI:A sugiere actualización manual, pero el fallo es en la integridad de la

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
