Summary

OpenRemote core (openremote-manager) before 1.31.0 does not check that inbound edge gateway events stay within the gateway's own descendant assets. Its reversible GatewayConnector.mapAssetId transform lets a gateway craft asset IDs that overwrite attributes on, or delete, assets in any tenant, breaking tenant isolation (CWE-639). An attacker who controls a registered gateway can do this with low privileges and no user interaction.

Description from the CNA

OpenRemote core (openremote-manager) before 1.31.0 does not perform realm or gateway-descendant authorization on inbound edge gateway events and maps event asset IDs only through the reversible GatewayConnector.mapAssetId transform. An attacker controlling a registered gateway can craft pre-image IDs in AttributeEvent or DELETE AssetEvent messages to overwrite attributes on, or delete, assets in any realm, breaking tenant isolation.
