Summary
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.
