CVE-2021-2271Network attack vector

Authenticated reading and modification of application data

Published Apr 22, 2021 · Updated Sep 26, 2024

Access control failure in Oracle Work in Process 12.1.3 and 12.2.3 through 12.2.8 allows remote authenticated users to read or alter data. Oracle identifies Resource Exceptions as the affected component but does not disclose the faulty operation or request-handling logic. Low-privileged HTTP access is required; successful exploitation permits complete reading and modification of accessible Work in Process data without affecting availability.
