In Eclipse Kura versions 5.0.0 through 5.6.2, the Wire Graph update functionality of the Kura Web UI, and the Wire Service REST API v1 (available since 5.1.0, org.eclipse.kura.rest.wire.provider), determine whether a configuration update targets a Wire Component, Driver or Asset from the factory identifier supplied in the request, instead of the actual factory of the existing component. An authenticated identity holding only the Wires management permission (kura.wires.admin for the Web UI, rest.wires.admin for the REST API) can therefore modify the configuration of existing components that are not part of the Wire Graph, including security-relevant ones, or replace existing components. This allows escalation to full administrative privileges and can disrupt the device. Modifying arbitrary components requires at least one Driver to be installed on the device. The issue is fixed in Eclipse Kura 5.6.3.
