An attacker could exploit this vulnerability by sending a crafted TACACS packet to the device. An exploit could allow the attacker to cause a partial DoS condition because the vpnmgr process could restart when parsing the crafted TACACS packet. Cisco has released software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available.
