Security readout for executives and security teams
This vulnerability can let a remote attacker crash the Embedded Services Processor on affected Cisco ASR 1000 routers, causing a denial of service. It is limited to specific older Cisco IOS XE 2.x and 2.5.x releases. No active exploitation is cited in the provided sources. Exposure is most likely where Cisco ASR 1000 routers still run the listed vulnerable IOS XE trains and process untrusted IPv4 or IPv6 traffic. Evidence does not identify other Cisco platforms or later software trains as affected. Treat this as a network availability risk for legacy ASR 1000 deployments. Prioritize if these routers support customer-facing, WAN, or edge services. Urgency is lower where the affected software is no longer present. Mitigation focus: Inventory Cisco ASR 1000 routers and record exact IOS XE versions.; Upgrade affected IOS XE 2.x systems to 2.4.3 or later.; Upgrade affected IOS XE 2.5.x systems to 2.5.1 or later..
