A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.
