CVE-2013-1191: Cisco NX-OS 6.1 before 6.1(5) on Nexus 7000 devices, when local authentication and multiple VDCs are enable...

Security readout for executives and security teams

This flaw affects Cisco Nexus 7000 switches running certain NX-OS 6.1 releases. In a specific configuration, an authenticated SSH user could cross into privileges for a virtual device context they should not control. The business risk is unauthorized changes inside core network infrastructure. Exposure appears limited to Nexus 7000 environments using affected NX-OS 6.1 builds, local authentication, multiple VDCs, and reachable management SSH. Organizations without Nexus 7000 VDC deployments are unlikely to be affected based on the supplied sources. Prioritize remediation where Nexus 7000 devices segment production, tenant, or regulated networks. This is not shown as actively exploited, but affected core switches carry high operational consequence if privilege boundaries fail. Mitigation focus: Upgrade affected Nexus 7000 NX-OS 6.1 systems to 6.1(5) or later vendor-fixed guidance.; Review Cisco advisory cisco-sa-20140521-nxos for exact fixed releases and caveats.; Restrict SSH management access to trusted administrative networks..
