Attack-Flow Graph

Executive Summary

This is a vulnerability in the JDBC component of Oracle Database Server affecting versions 19.3-19.31, 21.3-21.22, and 23.4.0-23.26.2. It allows a high privileged attacker with network access via Oracle Net to potentially take over the JDBC component. Exploitation requires human interaction from someone other than the attacker.

Detection Guidance

Detection requires checking Oracle Database Server versions 19.3-19.31, 21.3-21.22, or 23.4.0-23.26.2. Verify installed versions using Oracle utilities like SQL*Plus with SELECT * FROM v$version. Monitor network traffic for suspicious JDBC connections to Oracle Net ports.

Impact Analysis

If exploited, this vulnerability could lead to a complete takeover of the JDBC component in Oracle Database Server. This may result in unauthorized access to sensitive data, modification or deletion of data, and disruption of database services, potentially causing significant operational and security issues.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of sensitive data, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Organizations using affected Oracle Database versions may face legal penalties, reputational damage, and loss of customer trust if data breaches occur due to this vulnerability.

Mitigation Strategies

Apply the latest Oracle Critical Patch Update (CPU) for your affected Database Server version immediately. Disable unnecessary network access to the JDBC component and restrict privileges to only required users. Monitor Oracle security advisories for updates.
