CVE-2025-30751

Estado: ModificadaAlta (8.8)—

Vulnerability in the Oracle Database component of Oracle Database Server. Supported versions that are affected are 19.27 and 23.4-23.8. Easily exploitable vulnerability allows low privileged attacker having Create Session, Create Procedure privilege with network access via Oracle Net to compromise Oracle Database. Successful attacks of this vulnerability can result in takeover of Oracle Database. CVSS 3.1 Base Score 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

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/AC:L/PR:L indica acceso remoto con privilegios bajos. CWE-863 (Improper Authorization) permite escalada. La pista sugiere T1210 + T1078 (acceso a cuentas); el texto cita 'takeover' (confirmación de impacto total: confidencialidad, integridad, disponibilidad).

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.
