Cisco ONS IP/LAN ACK denial of service
| cisco-ons-iplan-ack-dos (25643) |  Medium Risk |
Description:
Multiple Cisco Optical Networking System (ONS) Multi-service Provisioning Platform (MSPP) devices are vulnerable to a denial of service attack. If IP is configured on the LAN interface, which is enabled by default, a remote attacker could launch an ACK denial of service attack against multiple remote management ports. This would cause the control cards on the targeted network entity to consume all available memory resources and possibly reset.
Consequences:
Denial of Service
Remedy:
Refer to Cisco Security Advisory cisco-sa-20060405-ons for upgrade or suggested workaround information. See References.
