Authenticated code execution via command delimiters
Published May 21, 2026 · Updated May 21, 2026
Command injection in Honeywell Control Network Module 100.1 through 110.2 allows remote authenticated users to execute commands via its web interface. The interface fails to neutralize command delimiters before incorporating attacker-controlled input into a command; Honeywell has not identified the affected handler or parameter. High-privilege access to the network-reachable interface is required, and successful injection grants code execution that can compromise the device and connected operations.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
