Descriptions

A vulnerability in the audit logging component of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & Presence Service, Cisco Unity Connection, Cisco Emergency Responder, and Cisco Prime License Manager could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system. The vulnerability is due to the storage of certain unencrypted credentials. An attacker could exploit this vulnerability by accessing the audit logs on an affected system and obtaining credentials that they may not normally have access to. A successful exploit could allow the attacker to use those credentials to discover and manage network devices.

Una vulnerabilidad en el componente de registro de auditoría de Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & amp; Presence Service, Cisco Unity Connection, Cisco Emergency Responder y Cisco Prime License Manager, podría permitir a un atacante remoto autenticado visualizar información confidencial en texto sin cifrar en un sistema afectado. La vulnerabilidad es debido al almacenamiento de determinadas credenciales no cifradas. Un atacante podría explotar esta vulnerabilidad accediendo a los registros de auditoría en un sistema afectado y obteniendo credenciales a las que normalmente no tiene acceso. Una explotación con éxito podría permitir al atacante usar esas credenciales para detectar y administrar dispositivos de red.
