CVE-2024-21093Network attack vector

Authenticated disclosure of Java VM data

Published Apr 16, 2024 · Updated Nov 6, 2024

Information disclosure in Oracle Database Java VM 19.3 through 19.22 and 21.3 through 21.13 allows remote authenticated users to read critical data. Oracle has not published the flawed Java VM routine or the operation it performs incorrectly on untrusted input. Exploitation requires Oracle Net access, high attack complexity, and both Create Session and Create Procedure privileges; the reported consequence is disclosure of Java VM-accessible data.
