Authenticated user enumeration via distinguishable RFC responses

Published Oct 14, 2025 · Updated Oct 14, 2025

Observable response discrepancy in SAP Financial Service Claims Management allows remote authenticated users to enumerate accounts through crafted RFC calls. The ICL_USER_GET_NAME_AND_ADDRESS function returns distinguishable responses for supplied user identifiers and can expose associated name and address data. Valid SAP credentials and network access to the RFC interface are required; successful queries disclose account existence and related personal data.
