A vulnerability in the backup feature of Cisco UCS Central Software could allow an attacker with access to a backup file to learn sensitive information that is stored in the full state and configuration backup files.
This vulnerability is due to a weakness in the encryption method that is used for the backup function. An attacker could exploit this vulnerability by accessing a backup file and leveraging a static key that is used for the backup configuration feature. A successful exploit could allow an attacker with access to a backup file to learn sensitive information that is stored in full state backup files and configuration backup files, such as local user credentials, authentication server passwords, Simple Network Management Protocol (SNMP) community names, and the device SSL server certificate and key.
The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered.
