Successful exploitation of any of the two command injection vulnerabilities could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system with elevated privileges. Successful exploitation of the Management GUI Denial of Service Vulnerability could cause several critical processes to become unresponsive and make the affected system unstable. Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.
