Affected Components Description The SAP HANA XS Administration Tool is a web application used to administer and maintain the HANA XS Engine. 5. Vulnerability Details Functions within SAP HANA XS Administration Tool do not sufficiently encode/filter output parameters, resulting in a reflected cross-site scripting issue. A reflected cross-site scripting attack can be used to non-permanently deface or modify displayed content from a Web site. Reflected cross-site scripting can be used to steal another user's authentication information, such as data relating to their current session. An attacker who gains access to this data may use it to impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, the security of the application may be fully compromised. Technical details about this issue are not disclosed at this moment with the purpose of providing enough time to affected customers to patch their systems and protect against the exploitation of the described vulnerability. 6. Solution SAP has released SAP Note 1993349 which provides patched versions of the affected components. The patches can be downloaded from https://service.sap.com/sap/support/notes/1993349. Onapsis strongly recommends SAP customers to download the related security fixes and apply them to the affected components in order to reduce business risks. 7.
