Unauthenticated shutdown via out-of-bounds firmware write
Published Jan 29, 2025 · Updated Feb 22, 2025
Out-of-bounds writes in Moxa switch firmware allow remote attackers to shut down affected devices via Moxa Service interfaces. Moxa has not identified the firmware component or input field; it states only that insufficient validation permits data to be written beyond a buffer boundary. Exploitation is unauthenticated and requires network reachability to an affected service, and successful attacks interrupt switching operations by shutting down the device.

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.
