Security readout for executives and security teams
This flaw can let an unauthenticated remote attacker crash both control function instances in Cisco VPC-DI, forcing the whole virtual packet core to reload. For a carrier or service provider, that means subscriber disconnections and a denial-of-service event, not data theft. Exposure is likely limited to organizations operating Cisco VPC-DI 19.2 through 21.0 where both CF DI network addresses can receive IPv4 UDP traffic from an attacker-controlled path. Treat this as high priority for affected packet-core environments because a successful attack can disconnect all subscribers on the affected system. Urgency depends on whether the CF DI addresses are reachable from untrusted networks. Mitigation focus: Check Cisco advisory cisco-sa-20170621-vpc for fixed releases or official workarounds.; Restrict IPv4 UDP reachability to DI network addresses for both CF instances.; Prioritize remediation for production VPC-DI systems carrying subscriber traffic..
