What is CVE-2026-20037?

A vulnerability in the Cisco UCS Manager Software enables authenticated users with read-only privileges to exploit unnecessary permissions, allowing them to modify files and execute unauthorized actions within the system. Attackers can authenticate as read-only users to access the NX-OS CLI, potentially creating or overwriting files in the file system. This situation poses a risk of limited privileged actions being executed on the affected devices, thereby compromising system integrity.
