Improper access control in SAP NetWeaver AS Java (Object Analyzing Service) 7.50 allows remote attackers to read server settings and data. The service permits unauthenticated attachment to an open interface and exposes a naming and directory API without required authorization checks. Network reachability to the interface is required; exploitation grants read-only access, with no ability to modify data or interrupt service.
