A vulnerability in Cisco ACNS RealServer RealSubscriber may allow a remote attacker to cause a denial of service on an affected device via malformed IP packets.
Cisco Application and Content Networking System (ACNS) is an integrated caching and content-delivery platform. ACNS 5.1 includes RealServer as an optional component. RealSubscriber is RealServer configured for subscriber-only mode. RealSubscriber is disabled by default. Specially crafted packets may cause RealSubscriber to consume 100% of the CPU of an affected device. A reboot of the device is required to recover.
