CVE-2025-54996

Estado: AnalizadaAlta (7.2)—

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, accounts with access to highly-privileged identity entity systems in root namespaces were able to increase their scope directly to the root policy. While the identity system allowed adding arbitrary policies, which in turn could contain capability grants on arbitrary paths, the root policy was restricted to manual generation using unseal or recovery key shares. The global root policy was not accessible from child namespaces.

This issue is fixed in version 2.3.2. To workaround this vulnerability, use of denied_parameters in any policy which has access to the affected identity endpoints (on identity entities) may be sufficient to prohibit this type of attack.

CVSS

En las versiones 2.3.1 y anteriores, las cuentas con acceso a sistemas de entidades de identidad con privilegios elevados en espacios de nombres raíz podían ampliar su alcance directamente a la política raíz. Si bien el sistema de identidad permitía añadir políticas arbitrarias, que a su vez podían contener concesiones de capacidad en rutas arbitrarias, la política raíz se limitaba a la generación manual mediante recursos compartidos de claves de recuperación o desbloqueo. La política raíz global no era accesible desde los espacios de nombres secundarios. Este problema se solucionó en la versión 2.3.2. Para solucionar esta vulnerabilidad, el uso de \"denegated_parameters\" en cualquier política que tenga acceso a los endpoints de identidad afectados (en entidades de identidad) podría ser suficiente para impedir este tipo de ataque."
