What it is about

Der Cisco Evolved Programmable Network (EPN) Manager ist eine All-in-One-Managementlösung für die Konvergenz von paketorientierten und optischen Netzwerken. Cisco Prime Infrastructure kombiniert die Wireless-Fähigkeiten von Cisco Prime Network Control System (NCS) und die drahtgebundenen Fähigkeiten von Cisco Prime LAN Management Solution (LMS) mit den Applikations- Performance-Monitoring- und Troubleshooting-Fähigkeiten von Cisco Prime Assurance Manager. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Cisco Evolved Programmable Network Manager und Cisco Prime Infrastructure ausnutzen, um falsche Informationen darzustellen.
