Summary

Cryptographic issues in the Cisco Nexus 1000v could allow an unauthenticated, remote attacker to to inject traffic or eavesdrop on the communications between a Virtual Supervisor Module (VSM) and a Virtual Ethernet Module (VEM).

The issues are due to errors in the implementation of the cryptography employed for VSM to VEM communications. An attacker must have access to the Layer 2 management VLAN, or the Layer 3 management traffic to exploit these issues.
Cisco would like to thank Felix 'FX' Lindner, Recurity Labs GmbH, for reporting this issue to us.
