Attack-Flow Graph

Executive Summary

This is a vulnerability in the RDBMS 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 to perform unauthorized updates, inserts, or deletes on some database-accessible data.

Detection Guidance

This vulnerability requires high privileged access and network access via Oracle Net. Detection involves monitoring Oracle Database Server logs for unauthorized data modifications or unusual network access patterns. Check Oracle alert logs and audit logs for suspicious activities related to data changes.

Impact Analysis

The impact includes unauthorized modification of data, which could lead to data corruption or integrity issues. However, the attack requires high privileges and network access, reducing the risk for most users.

Compliance Impact

This vulnerability could potentially violate compliance requirements that mandate data integrity and protection, such as GDPR or HIPAA, if exploited to alter sensitive data. However, the low CVSS score suggests limited impact.

Mitigation Strategies

Apply the latest Oracle Critical Patch Update (CPU) for your affected Oracle Database Server version to address the RDBMS vulnerability. Ensure only trusted users have high privileges and restrict network access via Oracle Net to minimize attack surface.
