CVE-2025-54997

Estado: AnalizadaCrítica (9.1)—

OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. In versions 2.3.1 and below, some OpenBao deployments intentionally limit privileged API operators from executing system code or making network connections. However, these operators can bypass both restrictions through the audit subsystem by manipulating log prefixes. This allows unauthorized code execution and network access that violates the intended security model. This issue is fixed in version 2.3.2. To workaround, users can block access to sys/audit/* endpoints using explicit deny policies, but root operators cannot be restricted this way.

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.

Operadores privilegiados (PR:H) en OpenBao explotan vulnerabilidad de inyección de código en el subsistema de auditoría para ejecutar código y acceso de red, eludiendo restricciones de seguridad intencionadas. CWE-94 confirma ejecución de código dinámico.

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.

En las versiones 2.3.1 y anteriores, algunas implementaciones de OpenBao limitan intencionalmente la ejecución de código del sistema o el establecimiento de conexiones de red por parte de operadores de API privilegiados. Sin embargo, estos operadores pueden eludir ambas restricciones a través del subsistema de auditoría manipulando los prefijos de registro. Esto permite la ejecución de código no autorizado y el acceso a la red que infringe el modelo de seguridad previsto. Este problema se solucionó en la versión 2.3.2. Como solución alternativa, los usuarios pueden bloquear el acceso a los endpoints sys/audit/* mediante políticas de denegación explícitas, pero los operadores raíz no pueden restringirse de esta forma."
