Symptom
A vulnerability in the command-line interface (CLI) of Cisco NX-OS System Software could allow an authenticated, local attacker to read the contents of arbitrary files.
The vulnerability is due to insufficient input validation for a specific CLI command. An attacker could exploit this vulnerability by issuing a crafted command on the CLI. An exploit could allow the attacker unauthorized access to read arbitrary files on the underlying local file system.
Note: On products that support multiple Virtual Device Contexts (VDC) this could allow an attacker to read files from any VDC.
