CVE-2017-16687
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.
Does this matter?
Lower severity and a low EPSS score (1.30%). Track it; it rarely justifies an emergency change on its own.
