Technical description

A vulnerability in the CLI of Cisco AsyncOS for Secure Web Appliance could allow an authenticated, local attacker to execute arbitrary commands and elevate privileges to root.

This vulnerability is due to insufficient validation of user-supplied input for the CLI. An attacker could exploit this vulnerability by authenticating to the system and executing a crafted command on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. To successfully exploit this vulnerability, an attacker would need at least guest credentials.

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.
