Security readout for executives and security teams

CVE-2012-1357 is a Cisco NX-OS denial-of-service issue affecting Nexus 5000 switches running NX-OS 5.0 and 5.1. A remote attacker can trigger a device reload using IGMP packets, disrupting switching services. The provided sources do not include CVSS, public exploitation, or a specific fixed version. Exposure is most likely in legacy Cisco Nexus 5000 environments still running NX-OS 5.0 or 5.1 with IGMP or multicast traffic reachable from untrusted or broad internal network segments. Prioritize if Nexus 5000 switches remain in production on NX-OS 5.0 or 5.1, especially in data center paths where reloads would disrupt critical services. Otherwise, treat as a legacy exposure verification item. Mitigation focus: Inventory Cisco Nexus 5000 switches and NX-OS versions.; Check Cisco guidance for CSCts46521 and applicable fixed releases.; Upgrade affected devices if Cisco confirms a fixed supported release..
