Detail

a. VMware ESXi and ESX NFC Protocol Unhandled Exception

VMware ESXi and ESX contain a vulnerability in the handling of the Network File Copy (NFC) protocol. To exploit this vulnerability, an attacker must intercept and modify the NFC traffic between ESXi/ESX and the client. Exploitation of the issue may lead to a Denial of Service.

To reduce the likelihood of exploitation, vSphere components should be deployed on an isolated management network

VMware would like to thank Alex Chapman of Context Information Security for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1661 to this issue.
