Rockwell Automation recommends users upgrade to FRN 15.2(6)E1 or later. Updated software can be downloaded at:

http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?famID=15

Rockwell Automation has provided knowledge base article number 1073268 on their website at the following location to
address these vulnerabilities:

Rockwell Automation also recommends implementing the following mitigations in addition to upgrading the software
version:

Cisco has released new Snort Rules at https://www.cisco.com/web/software/286271056/117258/sf-rules-2018-03-29-new.html
to help address the following vulnerabilities:

- CVE-2018-0171 - Snort Rule 46096 and 46097
- CVE-2018-0156 - Snort Rule 41725
- CVE-2018-0174 - Snort Rule 46120
- CVE-2018-0172 - Snort Rule 46104
- CVE-2018-0173 - Snort Rule 46119
- CVE-2018-0158 - Snort Rule 46110

Cisco adds the following notes for the Smart Install vulnerabilities (CVE-2018-0171 and CVE-2018-0156):

- Smart Install is turned off by express setup; however, upgraded switches but not re-setup may have it enabled.
- Disable the Smart Install feature with the no vstack configuration command if it is not needed or once setup is
complete.
- Users who do use the feature—and need to leave it enabled—can use ACLs to block incoming traffic on TCP port 4786.

CVE-2018-0167 and CVE-2018-0175 have no specific mitigations in place. See the following Cisco Vulnerability advisory
for more details:

https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180328-lldp

Rockwell Automation also recommends users implement the following general security guidelines:

- Help minimize network exposure for all control system devices and/or systems, and confirm that they are not accessible
from the Internet.
- Locate control system networks and devices behind firewalls, and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may
have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as
secure as the connected devices.");
