Estado: AnalizadaBaja (3.3)—

IBM Db2 Mirror for i 7.6, 7.5, and 7.4 could allow a local attacker to obtain sensitive information due to the use of the AES Electronic Codebook (ECB) mode for encryption.

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 local (AV:L/PR:L) en cifrado débil (ECB mode) que permite a atacante con acceso local extraer información sensible de Db2 Mirror for i.

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.
