Description
The vulnerability allows a local attacker to execute arbitrary shell commands.
The weakness exists in the CLI command-parsing code of the Cisco StarOS operating system due to insufficient sanitization of commands before inserting them into Linux shell commands. A local attacker can break from the StarOS CLI, submit and execute a specially crafted CLI command with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
