Description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the CLI of Cisco NX-OS System Software due to insufficient input validation of command arguments to the CLI parser. A local attacker can inject specially crafted command arguments into a vulnerable CLI command and execute arbitrary commands at the user's privilege level.
Successful exploitation of the vulnerability may result in system compromise.
