CVE-2025-53047

Vulnerability in the Portable Clusterware component of Oracle Database Server. Supported versions that are affected are 19.3-19.28, 21.3-21.19 and 23.4-23.9. Easily exploitable vulnerability allows unauthenticated attacker with network access via Bonjour to compromise Portable Clusterware. While the vulnerability is in Portable Clusterware, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized read access to a subset of Portable Clusterware accessible data. CVSS 3.1 Base Score 5.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N).

Summary		(es) Vulnerabilidad en el componente Portable Clusterware de Oracle Database Server. Las versiones compatibles que están afectadas son 19.3-19.28, 21.3-21.19 y 23.4-23.9. Vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso a la red a través de Bonjour comprometer Portable Clusterware. Aunque la vulnerabilidad está en Portable Clusterware, los ataques pueden impactar significativamente productos adicionales (cambio de alcance). Ataques exitosos de esta vulnerabilidad pueden resultar en acceso de lectura no autorizado a un subconjunto de datos accesibles de Portable Clusterware. Puntuación Base CVSS 3.1 de 5.8 (impactos en la Confidencialidad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N).
