Synopsis

The remote SAP NetWeaver AS Java server may be missing an authorization check

Description

The MigrationService, which is part of SAP NetWeaver versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not perform an authorization check. This might allow an unauthorized attacker to access configuration objects, including such that grant administrative privileges. This could result in complete compromise of system confidentiality, integrity, and availability.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the vendor advisory.
