CVE-2019-2909

Name of the Vulnerable Software and Affected Versions Oracle Database Server versions 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c, 19c

Description The issue is related to insufficient input validation in the Java VM component of Oracle Database Server. This can be exploited by a remote attacker to gain read, modify, add, or delete access to data using multiple network protocols. Successful attacks can result in unauthorized access to critical data or all Java VM accessible data.

Recommendations For versions 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c, 19c, update to a version that includes the fix for this issue to prevent exploitation. As a temporary workaround, consider restricting network access to the Java VM component to minimize the risk of exploitation. Restrict access to critical data to prevent unauthorized modification or deletion.
