The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by executing a specific CLI command that includes crafted arguments. A successful exploit could allow the attacker to execute commands on the underlying OS with root privileges. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
