4. Affected Components Description

SAP Business Objects allows a remote user, potentially using a Guest account if enabled, to perform CORBA calls to resources that should be restricted by correctly checking the privileges of the user performing the request.

5. Vulnerability Details

Using CORBA calls it is possible to escalate privileges from any valid user to System privileges in BusinsessObjects. The System Account can perform any action in BusinessObjects.

An unauthenticated attacker (if Guest user is enabled, so no credentials are required) can obtain the SI_PLATFORM_SEARCH_SERVER_LOGON_TOKEN via CORBA. This token can be used, also via CORBA, to perform actions as SYSTEM, thus escalating privileges.

6. Solution

SAP has released SAP Note 2039905 which provide patched versions of the affected components.

The patches can be downloaded from https://service.sap.com/sap/support/notes/2039905

Onapsis strongly recommends SAP customers to download the related security fixes and apply them to the affected components in order to reduce business risks.
