CVE-2021-2083Network attack vector

Unauthenticated data access via User Responsibilities

Published Jan 20, 2021 · Updated Sep 26, 2024

Authentication bypass in Oracle iSupport 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 allows remote attackers to access critical data via HTTP. The User Responsibilities component accepts an unauthenticated request after interaction by another person, but Oracle has not published the specific authentication-check operation or code locus. Successful exploitation can also permit unauthorized updates, inserts, or deletes to some iSupport data and may affect connected products.
