SAP HANA database is vulnerable to privilege escalation allowing an attacker with valid credentials of any user to switch to another user potentially gaining administrative access. This exploit could result in a total compromise of the system�s confidentiality, integrity, and availability.

The user self-service tools of SAP HANA extended application services, classic user self-service, a part of SAP HANA Database versions 1.00 and 2.00, can be misused to enumerate valid and invalid user accounts. An unauthenticated user could use the error messages to determine if a given username is valid.

In systems using the optional capture & replay functionality of SAP HANA, 1.00 and 2.00, (see SAP Note 2362820 for more information about capture & replay), user credentials may be stored in clear text in the indexserver trace files of the control system. An attacker with the required authorizations on the control system may be able to access the user credentials and gain unauthorized access to data in the captured or target system.

Under certain conditions SAP HANA, 1.00, 2.00, allows an unauthenticated attacker to access information which would otherwise be restricted. An attacker can misuse the authentication function of the SAP HANA server on its SQL interface and disclose 8 bytes of the server process memory. The attacker cannot influence or predict the location of the leaked memory.

A remote unauthenticated attacker, SAP HANA 1.00 and 2.00, could send specially crafted SOAP requests to the SAP Startup Service and disclose information such as the platform's hostname.
