Security readout for executives and security teams
This CVE describes a memory leak in Cisco IOS before 15.0(1)XA5. A remote attacker might cause a denial of service by sending a crafted SIP REGISTER message over UDP, consuming device memory. The direct business risk is voice or routing service disruption on exposed Cisco IOS infrastructure. Exposure is most likely on Cisco IOS devices running versions before 15.0(1)XA5 where UDP SIP REGISTER traffic can reach the device. The source bundle does not identify specific router models, configurations, or CPEs. Treat as a service availability risk for legacy Cisco IOS environments. Prioritize internet-facing or voice-adjacent devices first, especially where outages would affect customer communications or branch connectivity. Mitigation focus: Inventory Cisco IOS devices and identify versions before 15.0(1)XA5.; Review Cisco guidance for CSCtg41733 and applicable fixed releases.; Upgrade affected devices to 15.0(1)XA5 or a supported fixed release..
