CVE-2023-39593

Estado: AnalizadaMedia (5.6)—💥 PoC

Insecure permissions in the sys_exec function of MariaDB v10.5 allows authenticated attackers to execute arbitrary commands with elevated privileges. 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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
