CVE-2023-22075

Name of the Vulnerable Software and Affected Versions Oracle Database Server versions 19.3 through 19.20 Oracle Database Server versions 21.3 through 21.11

Description The issue is related to insufficient input validation in the Oracle Database Sharding component. It allows a high-privileged attacker with network access via Oracle Net to compromise Oracle Database Sharding, resulting in a partial denial of service (partial DOS). Successful attacks require human interaction from a person other than the attacker.

Recommendations For versions 19.3 through 19.20, update to a version outside of this range to resolve the issue. For versions 21.3 through 21.11, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting access to the Oracle Database Sharding component to minimize the risk of exploitation.
