The SQL interface in SAP HANA DB 1.00.091.00.1418659308 provides different error messages for failed login attempts depending on whether the username exists and is locked when the detailederroronconnect option is not supported or is configured as "False," which allows remote attackers to enumerate database users via a series of login attempts, aka SAP Security Note 2216869.

SAP HANA DB 1.00.091.00.1418659308 allows remote attackers to obtain sensitive topology information via an unspecified HTTP request, aka SAP Security Note 2176128.

The Extended Application Services (aka XS or XS Engine) in SAP HANA DB 1.00.091.00.1418659308 allows local users to obtain sensitive password information via vectors related to passwords in Web Dispatcher trace files, aka SAP Security Note 2148905.

SAP HANA Database, version - 2.0, does not correctly validate the username when performing SAML bearer token-based user authentication. It is possible to manipulate a valid existing SAML bearer token to authenticate as a user whose name is identical to the truncated username for whom the SAML bearer token was issued.

SAP HANA Database, versions - 1.0, 2.0, accepts SAML tokens with MD5 digest, an attacker who manages to obtain an MD5-digest signed SAML Assertion issued for an SAP HANA instance might be able to tamper with it and alter it in a way that the digest continues to be the same and without invalidating the digital signature, this allows them to impersonate as user in HANA database and be able to read the contents in the database.
