Summary

A recently announced vulnerability in certain versions of the command line interface (CLI) of Cisco's NX-OS software could allow an attacker to run arbitrary commands as the root user. This vulnerability stems from insufficient validation of command line arguments passed to certain NX-OS CLI commands. Cisco has classified this vulnerability as "Medium"; an attacker must already have Administrator credentials in order to exploit this vulnerability.
