CVE-2022-21498Network attack vector

Data modification via undisclosed Java VM flaw

Published Apr 19, 2022 · Updated Sep 24, 2024

Improper authorization in the Java VM component of Oracle Database 12.1.0.2, 19c, and 21c allows remote authenticated users to modify data. Oracle has not published the code locus or incorrect operation that permits the Java VM compromise. Network access through multiple protocols and Create Procedure privilege are required; exploitation creates, deletes, or modifies critical or Java VM-accessible data.
