Cisco ASR 1000 devices with software before 3.8S, when BDI routing is enabled, allow remote attackers to cause a denial of service (device reload) via crafted (1) broadcast or (2) multicast ICMP packets with fragmentation, aka Bug ID CSCub55948.

Security readout for executives and security teams

This flaw can let a remote attacker crash and reload a Cisco ASR 1000 router in a specific configuration. The affected condition is software before 3.8S with BDI routing enabled. For businesses, the concern is network outage, not data theft, and exposure depends on whether legacy ASR 1000 systems remain in service. Likely limited to legacy Cisco ASR 1000 deployments running pre-3.8S software with BDI routing enabled and reachable by relevant broadcast or multicast ICMP traffic. Treat as a targeted network availability risk. It is most urgent where legacy ASR 1000 routers support critical connectivity and still run pre-3.8S software with BDI routing enabled. Mitigation focus: Identify any Cisco ASR 1000 routers still running software before 3.8S.; Upgrade affected devices to Cisco software 3.8S or later where supported.; Review Cisco release notes and bug CSCub55948 guidance for platform-specific caveats..
