Description

A vulnerability in the configuration backup feature of Cisco Nexus Dashboard could allow an attacker who has the encryption password and access to Full or Config-only backup files to access sensitive information.

This vulnerability exists because authentication details are included in the encrypted backup files. An attacker with a valid backup file and encryption password from an affected device could decrypt the backup file. The attacker could then use the authentication details in the backup file to access internal-only APIs on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.
