Descriptions

A vulnerability in the database user privileges of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. This vulnerability is due to insufficient file permission restrictions. An attacker could exploit this vulnerability by sending a crafted command from the API to the application. A successful exploit could allow the attacker to read arbitrary files on the underlying operating system of the affected device. The attacker would need valid user credentials to exploit this vulnerability.

Una vulnerabilidad en los privilegios del usuario de la base de datos de Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), y Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) podría permitir a un atacante autenticado y remoto leer archivos arbitrarios en el sistema operativo subyacente de un dispositivo afectado. Esta vulnerabilidad es debido a una insuficiencia de restricciones de permisos de archivos. Un atacante podría explotar esta vulnerabilidad mediante el envío de un comando diseñado desde la API a la aplicación. Una explotación con éxito podría permitir al atacante leer archivos arbitrarios en el sistema operativo subyacente del dispositivo afectado. El atacante necesitaría credenciales de usuario válidas para explotar esta vulnerabilidad
