Unspecified vulnerability in Cisco IOS 12.2SB before 12.2(33)SB10 and 15.0S before 15.0(1)S3a on Cisco 10000 series routers allows remote attackers to cause a denial of service (device reload) via a sequence of crafted ICMP packets, aka Bug ID CSCtk62453.

Security readout for executives and security teams

This issue can make affected Cisco 10000 series routers reload after receiving crafted ICMP traffic. For a business, the main risk is network outage, not data theft. The source bundle identifies fixed Cisco IOS releases, but does not provide CVSS scoring or evidence of active exploitation. Exposure is likely limited to Cisco 10000 series routers on the named IOS trains. Risk is higher where ICMP can reach the router control plane from untrusted networks. Treat this as a continuity risk for legacy Cisco routing infrastructure. Prioritize verification and upgrade planning where affected routers support internet edge, customer connectivity, or critical WAN paths. Mitigation focus: Upgrade affected IOS 12.2SB systems to 12.2(33)SB10 or later.; Upgrade affected IOS 15.0S systems to 15.0(1)S3a or later.; Review Cisco advisory guidance for any platform-specific operational notes..
