Summary
Due to the lack of randomness in assigning Object Identifiers in the SAP NetWeaver AS JAVA IIOP service, an authenticated attacker with low privileges could predict the identifiers by conducting a brute force search. By leveraging knowledge of several identifiers generated close to the same time, the attacker could determine a desired identifier which could enable them to access limited system information. This poses a low risk to confidentiality without impacting the integrity or availability of the service.
