See the Cisco Adaptive Security Appliance Software SSL/TLS Denial of Service Vulnerability for additional information. A vulnerability in the CLI of Cisco FXOS Software could allow an authenticated, local attacker to inject arbitrary commands that are executed with root privileges. The vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
