CVE-2013-1181: n/a vulnerability

CVE-2013-1181: Cisco NX-OS on Nexus 5500 devices 4.x and 5.x before 5.0(3)N2(2), Nexus 3000 devices 5.x before 5.0(3)U3(2)...

Cisco NX-OS on Nexus 5500 devices 4.x and 5.x before 5.0(3)N2(2), Nexus 3000 devices 5.x before 5.0(3)U3(2), and Unified Computing System (UCS) 6200 devices before 2.0(1w) allows remote attackers to cause a denial of service (device reload) by sending a jumbo packet to the management interface, aka Bug IDs CSCtx17544, CSCts10593, and CSCtx95389.

Security readout for executives and security teams

This flaw can make certain Cisco switching and UCS infrastructure reload if the management interface receives an oversized packet. The business risk is service disruption, especially where management networks are reachable from broader enterprise or partner networks. Exposure is most likely in legacy Cisco Nexus 5500, Nexus 3000, or UCS 6200 environments still running the listed older NX-OS or UCS software, especially if management interfaces are not tightly isolated. Prioritize remediation where affected devices support critical production traffic or have broadly reachable management interfaces. For isolated management networks, treat this as planned infrastructure hygiene rather than an emergency. Mitigation focus: Upgrade Nexus 5500 to NX-OS 5.0(3)N2(2) or later.; Upgrade Nexus 3000 to NX-OS 5.0(3)U3(2) or later.; Upgrade UCS 6200 to version 2.0(1w) or later..
