CVE-2024-20280 | Cisco UCS Central Software Configuration Backup Static Key Vulnerability

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.

Base score Version Severity Vector Exploitability Impact Score source
6.3 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
