Tycon Systems TPDIN-Monitor-WEB3 versions 2.2.9 and prior are vulnerable to a use of hard-coded credential vulnerability. This could allow an attacker to intercept sensitive information or credentials.

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.

AV:A (red adyacente) + credenciales hardcodeadas (CWE-798) permite autenticación sin privilegios previos; acceso a credenciales almacenadas en el código.

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.
