An attacker could potentially exploit this vulnerability, leading to the ability to modify files on Honeywell Experion ControlEdge VirtualUOC and ControlEdge UOC . This exploit could be used to write a file that may result in unexpected behavior based on configuration changes or updating of files that could result in subsequent execution of a malicious application if triggered. Honeywell recommends updating to the most recent version of the product. See Honeywell Security Notification for recommendations on upgrading and versioning.
