Notes 2596535 and 2587369 deal with information disclosure vulnerabilities in SAP Business Process Automation (BPA) by Redwood and SAP HANA 1.0 and 2.0. Both notes carry a CVSS score of 7.5 or higher and could be exploited to leak sensitive system and user-related data. In the case of SAP HANA, user credentials may be stored in clear text in indexserver trace files. Attackers may be able to access systems using compromised credentials garnered from the files. This requires TRACE_ADMIN or CATALOG READ privileges. Access to these and other critical privileges in HANA systems should be monitored using SAP Solution Manager.
