CVE-2023-21959Network attack vector

Authenticated attachment-data disclosure

Published Apr 18, 2023 · Updated Sep 16, 2024

Information disclosure in Oracle iReceivables 12.2.3 through 12.2.12 allows remote authenticated users to read attachment data via HTTP. Oracle identifies the affected locus only as the Attachments component and has not published the request-handling error that exposes data. A low-privileged iReceivables account and network access to the web application are required; the reported consequence is limited to unauthorized reading of a subset of accessible data.
