CVE-2013-1209 is a vulnerability of currently unknown severity. The encryption functionality in the Virtual Supervisor Module (VSM) to Virtual Ethernet Module (VEM) communication component in Cisco NX-OS on the Nexus 1000V does not properly authenticate VSM/VEM packets, which allows remote attackers to disable packet-level encryption and integrity protection via crafted packets, aka Bug ID CSCud14710.. EPSS estimates a 0.76% chance of exploitation in the next 30 days.
