CVE-2021-2231Network attack vector

Authenticated data disclosure and modification

Published Apr 22, 2021 · Updated Sep 26, 2024

An undisclosed flaw in Oracle Installed Base 12.1.3 APIs allows remote authenticated users to read and alter application data over HTTP. Oracle identifies the affected locus only as the APIs component and does not disclose which authorization check or input-handling operation is defective. A low-privilege account and network access to the HTTP interface are required; successful exploitation permits complete reading and modification of Installed Base data but does not interrupt service.
