Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Business Process Automation (BPA) could allow an authenticated, remote attacker to elevate privileges to Administrator. These vulnerabilities are due to improper authorization enforcement for specific features and for access to log files that contain confidential information. An attacker could exploit these vulnerabilities either by submitting crafted HTTP messages to an affected system and performing unauthorized actions with the privileges of an administrator, or by retrieving sensitive data from the logs and using it to impersonate a legitimate privileged user. A successful exploit could allow the attacker to elevate privileges to Administrator.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Cisco Business Process Automation (BPA) podrían permitir a un atacante remoto autenticado elevar los privilegios a Administrador. Estas vulnerabilidades son debido a la aplicación inapropiada de la autorización para funcionalidades específicas y para el acceso a archivos de registro que contienen información confidencial. Un atacante podría explotar estas vulnerabilidades al enviar mensajes HTTP diseñados hacia un sistema afectado y llevando a cabo acciones no autorizadas con los privilegios de un administrador, o recuperando datos confidenciales de los registros y utilizándolos para hacerse pasar por un usuario legítimo con privilegios. Una explotación con éxito podría permitir al atacante elevar los privilegios a administrador
