CVE-2021-2364Network attack vector

Authenticated data access and modification

Published Jul 20, 2021 · Updated Sep 26, 2024

Authorization flaw in iSupplier Portal 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 allows remote authenticated users to read or alter data. Oracle identifies the Accounts component but has not published the faulty operation or input that defeats its intended authorization controls. A low-privileged account with HTTP access is required; exploitation exposes and permits changes to critical or all portal-accessible data.
