Security readout for executives and security teams
CVE-2013-1226 is a Cisco Nexus 7000 NX-OS denial-of-service issue. A maliciously crafted Ethernet frame can trigger a forwarding loop and service outage, potentially disrupting network availability. The provided sources do not include CVSS, affected version ranges, fixed releases, or workarounds. Exposure appears limited to Cisco Nexus 7000 devices running NX-OS in affected Ethernet forwarding scenarios. The bundle does not provide affected versions or configurations, so teams must validate against Cisco’s notice and internal network inventory. Treat this as an availability risk for core network infrastructure. Urgency depends on whether Nexus 7000 devices are deployed and affected, which the provided sources do not fully define. Mitigation focus: Review Cisco’s security notice for affected releases, fixed software, and workarounds.; Inventory Cisco Nexus 7000 devices and their NX-OS versions.; Prioritize remediation for Nexus 7000 devices carrying critical production traffic..
