CVE-2013-3467: Memory leak in the CLI component on Cisco Unified Computing System (UCS) 6100 Fabric Interconnect devices,...

Security readout for executives and security teams

CVE-2013-3467 is a local denial-of-service issue in Cisco UCS 6100 Fabric Interconnect devices. A user with CLI access can trigger a memory leak in the CLI component when no SPAN session exists, potentially causing memory exhaustion and a device reset. Exposure appears limited to organizations still operating Cisco UCS 6100 Fabric Interconnect devices and allowing local CLI access. Risk is higher where non-administrative local users can access operational show commands on production fabric interconnects. Treat this as a legacy infrastructure availability risk. It is not presented as internet-exploitable, but a reset of UCS fabric interconnect infrastructure could disrupt dependent compute workloads if vulnerable devices remain in production. Mitigation focus: Check Cisco advisory guidance for affected software and fixed releases.; Restrict CLI access to trusted administrators only.; Review role-based permissions for operational show commands..
