Technical details
The GatewayConnector.mapAssetId transform is mathematically reversible—an attacker who owns a gateway can invert it to craft asset IDs that map to any asset in any realm. Inbound gateway events skip realm and descendant authorization checks; onAttributeEvent and onAssetEvent (DELETE) process events based solely on the mapped asset ID without validating authorization scope. An authenticated gateway user can thus overwrite arbitrary attributes or delete assets across all tenants.
Affected products
- OpenRemote core before 1.31.0
