workarounds: value: xArrow has not responded to requests to work with CISA to mitigate these vulnerabilities. Users of these affected products who would like to see more responsible security are invited to contact xArrow customer support.
value: CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
    Disable web server implementation. Web server is disabled by default.
    Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
    Locate control system networks and remote 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 VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as its connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
