Descriptions

A vulnerability in the FUSE filesystem functionality for Cisco Application Policy Infrastructure Controller (APIC) software could allow an authenticated, local attacker to escalate privileges to root on an affected device. The vulnerability is due to insufficient input validation for certain command strings issued on the CLI of the affected device. An attacker with write permissions for files within a readable folder on the device could alter certain definitions in the affected file. A successful exploit could allow an attacker to cause the underlying FUSE driver to execute said crafted commands, elevating the attacker's privileges to root on an affected device.

Una vulnerabilidad en la funcionalidad del sistema de archivos FUSE (FUSE filesystem) para el software Application Policy Infrastructure Controller (APIC) de Cisco, podría permitir a un atacante local identificado escalar privilegios a root en un dispositivo afectado. La vulnerabilidad es debido a una comprobación de entrada insuficiente para ciertas cadenas de comando emitidas en la CLI del dispositivo afectado. Un atacante con permisos de escritura para archivos dentro de una carpeta legible en el dispositivo podría alterar ciertas definiciones en el archivo afectado. Una operación con éxito podría permitir a un atacante causar que el controlador FUSE subyacente ejecute dichos comandos creados, elevando los privilegios del atacante a root en un dispositivo afectado.
