4. MITIGATIONS

Mitsubishi Electric recommends that users take the following mitigations to minimize the risk of exploiting this vulnerability:

If you do not need to use the multi-agent notification feature, please uninstall it. The multi-agent notification feature is not included in the default installation of GENESIS64TM version 10.97.3 or later. For users engaging the multi-agent notification feature who do not also need to the Pager agent, please execute a custom installation of the multi-agent notification feature and skip the installation of the Pager agent.
Please configure the PCs with the affected product installed so that only an administrator can log in.
PCs with the affected product installed should be configured to block remote logins from untrusted networks and hosts, and from non-administrator users.
Block unauthorized access by using a firewall or virtual private network (VPN), etc., and allow remote login only to administrators when connecting the PCs with the affected product installed to the Internet.
Restrict physical access to the PC with the affected product installed and the network to which the PC is connected to prevent unauthorized physical access.
Do not click on web links in emails from untrusted sources. Also, do not open attachments in untrusted emails.
