Summary
SAP HANA Database (user self service tools) allows an unauthenticated user to send specially crafted requests that produce distinguishable responses, enabling enumeration of valid user accounts and email addresses. Successful exploitation could allow the attacker to enumerate valid user accounts, resulting in low impact on confidentiality, with no impact on integrity and availability of the application.
