CVE-2014-3341: The SNMP module in Cisco NX-OS 7.0(3)N1(1) and earlier on Nexus 5000 and 6000 devices provides different er...

Security readout for executives and security teams

This flaw can let a remote party learn which VLAN IDs exist on certain Cisco Nexus switches by observing different SNMP error behavior. It is information disclosure, not direct device takeover, but VLAN knowledge can support network mapping and later intrusion planning. Exposure is most likely where Cisco Nexus 5000 or 6000 switches run affected NX-OS versions and SNMP is reachable by users or networks that should not have infrastructure visibility. Handle as a targeted network infrastructure exposure. It does not indicate confirmed active exploitation or direct compromise, but it can reveal segmentation details that attackers value. Prioritize affected switches with broad SNMP reachability. Mitigation focus: Check Cisco’s CVE-2014-3341 notice for fixed releases or vendor workarounds.; Inventory Nexus 5000 and 6000 devices and record NX-OS versions.; Restrict SNMP access to trusted management hosts only..
