CVE-2021-2004Network attack vector

Authenticated data disclosure via undisclosed scripting flaw

Published Jan 20, 2021 · Updated Sep 26, 2024

Information disclosure in Oracle Siebel Core - Server Framework 20.12 and earlier allows remote authenticated users to read application data. Oracle identifies the affected locus as Integration - Scripting but has not disclosed the defective operation or the input that triggers it. Exploitation requires a low-privilege account and HTTP network access, and the reported consequence is limited to reading a subset of data accessible to the affected server scripting component.
