Cisco AsyncOS Content Security Management Appliance (SMA) Privilege Escalation Vulnerability
Description
A vulnerability in the user account management system of Cisco AsyncOS for Cisco Content Security Management Appliance (SMA) could allow an authenticated, local attacker to elevate their privileges to root.
