Detailsinfo

A vulnerability has been found in Cisco Unified Computing System Central Software and classified as problematic. Affected by this vulnerability is an unknown code of the component Backup. The manipulation with an unknown input leads to a hard-coded key vulnerability. The CWE definition for the vulnerability is CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. As an impact it is known to affect confidentiality. The summary by CVE is:

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 advisory is shared at sec.cloudapps.cisco.com. This vulnerability is known as CVE-2024-20280 since 11/08/2023. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600.001 for this issue.
