An attacker could potentially exploit this vulnerability, leading to files being read from the Honeywell Experion ControlEdge VirtualUOC and ControlEdge UOC. This exploit could be used to read files from the controller that may expose limited information from the device.
Honeywell recommends updating to the most recent version of the product. See Honeywell Security Notification for recommendations on upgrading and versioning.
This plugin only works with Tenable.ot.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.
Honeywell fixed the reported issues and advises users to upgrade to version referenced in the Security Notice
or CVE record.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Ensure the least-privilege user principle is followed.
- Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls and isolate them from business networks.
- 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.");
