Technical description

A vulnerability in the REST API of Cisco Catalyst Center could allow an authenticated, remote attacker to execute arbitrary commands in a restricted container as the root user.

This vulnerability is due to insufficient validation of user-supplied input in REST API request parameters. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to inject arbitrary commands that would then be executed in a restricted container with root privileges. To exploit this vulnerability, the attacker must have valid credentials for a user account with at least the role of Observer.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
