Privilege escalation via missing authorization checks
Published Mar 9, 2021 · Updated Aug 3, 2024
Missing authorization checks in SAP Bank Customer Accounts before listed component releases allow remote authenticated users to escalate privileges. SAP identifies the IS-B-BCA ABAP component, but its public record does not name the affected function or the authorization decision that omits the required check. A valid low-privileged account is required; successful exploitation permits unauthorized reading and modification of protected financial data without a published service-interruption impact.
