CVE-2023-26785

Estado: AnalizadaCrítica (9.8)—

MariaDB v10.5 was discovered to contain a remote code execution (RCE) vulnerability via UDF Code in a Shared Object File, followed by a "create function" statement. NOTE: this is disputed by the MariaDB Foundation because no privilege boundary is crossed.

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 CVSS AV:N/AC:L/PR:N sin interacción: explotación remota de aplicación expuesta. CWE-94 (code injection) y descripción de RCE vía UDF confirman ejecución de código arbitrario. Escalada de privilegios es potencial si se ejecuta con privilegios elevados.

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.
