CVE-2025-5662

Estado: AplazadaCrítica (9.8)—

A deserialization vulnerability exists in the H2O-3 REST API (POST /99/ImportSQLTable) that affects all versions up to 3.46.0.7. This vulnerability allows remote code execution (RCE) due to improper validation of JDBC connection parameters when using a Key-Value format. The vulnerability is present in the MySQL JDBC Driver version 8.0.19 and JDK version 8u112. The issue is resolved in version 3.46.0.8.

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.

Deserialization remota sin autenticación (AV:N/PR:N/UI:N) en REST API expuesta permite RCE. CWE-502 confirma deserialization insegura; JDBC+MySQL es ejecución de código.

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.
