CVE-2021-2101Network attack vector

Unauthenticated access to and modification of critical data

Published Jan 20, 2021 · Updated Sep 26, 2024

Unspecified flaw in Oracle One-to-One Fulfillment 12.1.1 through 12.1.3 and 12.2.3 through 12.2.10 allows remote attackers to read and alter data. Oracle identifies the Print Server as the affected component but has not published the flawed endpoint, parameter, or operation. Unauthenticated HTTP access is sufficient; exploitation permits disclosure and creation, deletion, or modification of critical or product-accessible data.
