CVE-2025-36421

Estado: Pendiente de análisisMedia (5.9)—

IBM Controller 11.0.0 through 11.0.1 FP7, and 11.1.0 through 11.1.3 FP1 transmits data in clear text that could allow an attacker to obtain sensitive information using man in the middle techniques.

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.

CWE-319 (transmisión en texto claro) + vector AV:N sin autenticación permite ataques MITM (T1557). Confidencialidad alta; impacto principal es lectura de datos sensibles (T1005) y captura de red (T1040).

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.
