high Nessus Plugin ID 148221
New! Plugin Severity Now Using CVSS v3

The remote device is missing a vendor-supplied security patch


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
