Multiple Cisco ONS devices control card denial of service
| cisco-ons-controlcard-dos (47940) |  Medium Risk |
Description:
Multiple Cisco ONS devices are vulnerable to a denial of service, caused by the improper handling of a steady stream of TCP traffic to the control cards. By establishing a connection to any open TCP port, a remote attacker could exploit this vulnerability to reset the node's control card resulting in a denial of service.
