Summary
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 issue exists because authentication details are included in the encrypted backup files.
Risk Assessment
An attacker could decrypt the backup file and use the authentication details to access internal-only APIs on the affected device, potentially leading to arbitrary command execution on the underlying operating system as the root user.
Recommendation
Immediately update Cisco Nexus Dashboard to a patched version and secure backup encryption passwords against unauthorized access.

Original NVD description (English source)
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.
