CVE-2022-21245Network attack vector

Authenticated unauthorized modification of database data

Published Jan 19, 2022 · Updated Sep 24, 2024

Improper privilege enforcement in Oracle MySQL Server 5.7.36 and earlier and 8.0.27 and earlier allows remote authenticated users to modify data. Oracle identifies the Server: Security: Privileges component but has not disclosed the faulty operation or the input that reaches it. A low-privileged account with MySQL Protocol access is required, and successful exploitation permits unauthorized updates, inserts, or deletions to some accessible data.
