Estado: AnalizadaCrítica (9.1)—

Unprotected transport of credentials vulnerability in syslink software AG Avantra on Linux, Windows allows Sniffing Attacks.

This issue affects Avantra: before 25.3.0.

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.

Vector AV:N/PR:N indica explotación remota sin privilegios (T1190). CWE-523 sobre transporte sin protección permite captura de credenciales (T1212) mediante sniffing/MITM (T1557).

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.
