Official Description

A vulnerability in the CLI and web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker with valid administrative privileges to execute arbitrary commands on the underlying operating system of an affected device. 

This vulnerability is due to insufficient input validation of command arguments that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device with root-level privileges.

Technical Analysis

CVE-2026-20036 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 6.5.
