Summary
=======
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to perform a command-injection attack on an affected device.
The vulnerability is due to insufficient input validation of command arguments. An attacker could exploit this vulnerability by injecting malicious command arguments into a vulnerable CLI command. A successful exploit could allow the attacker, authenticated as a privileged user, to execute arbitrary commands with root privileges.
Note: On products that support multiple virtual device contexts (VDC), this vulnerability could allow an attacker to access files from any VDC.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
