3Description
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.
Analysis
Cisco Nexus Dashboard configuration backup feature allows authenticated administrators to extract sensitive authentication credentials from encrypted backup files, enabling subsequent unauthorized access to internal APIs and arbitrary root-level command execution on the underlying operating system. The vulnerability requires possession of both a valid backup file and its encryption password, limiting exploitation to administrators or attackers with backup file access. …
