Descriptions

A vulnerability in Cisco NX-OS System Software could allow an authenticated, local attacker to bypass signature verification when loading a software image. The vulnerability is due to insufficient NX-OS signature verification for software images. An authenticated, local attacker could exploit this vulnerability to bypass signature verification and load a crafted, unsigned software image on a targeted device. The attacker would need valid administrator credentials to perform this exploit. This vulnerability affects the following products running Cisco NX-OS System Software: Multilayer Director Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches, Unified Computing System Manager. Cisco Bug IDs: CSCvf25045, CSCvf31495.

Una vulnerabilidad en Cisco NX-OS System Software podría permitir a un atacante local autenticado omitir la verificación de firmas cuando se carga una imagen de software. La vulnerabilidad se debe a una verificación de firmas NX-OS insuficiente para imágenes de software. Un atacante local autenticado podría explotar esta vulnerabilidad para omitir la verificación de firmas y cargar una imagen de software manipulada y sin firma en un dispositivo objetivo. El atacante necesitaría credenciales de administrador válidas para explotar esta vulnerabilidad. Esta vulnerabilidad afecta a los siguientes productos que ejecutan Cisco NX-OS System Software: Multilayer Director Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches y Unified Computing System Manager. Cisco Bug IDs: CSCvf25045, CSCvf31495.
