CVE-2021-35558

Estado: ModificadaMedia (4.3)—

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1, 19c and 21c. Easily exploitable vulnerability allows low privileged attacker having Create Table privilege with network access via Oracle Net to compromise Core RDBMS. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Core RDBMS. CVSS 3.1 Base Score 4.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L).

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).
