"A vulnerability in the CLI command permissions of Cisco IOS Software could allow an authenticated, local attacker to
retrieve the password for Common Industrial Protocol (CIP) and then remotely configure the device as an administrative
user. This vulnerability exists because incorrect permissions are associated with the show cip security CLI command. An
attacker could exploit this vulnerability by issuing the command to retrieve the password for CIP on an affected device.
A successful exploit could allow the attacker to reconfigure the device
