- Implement strict network segmentation to isolate Oracle Product Hub from untrusted networks.
- Enhance monitoring and logging for suspicious activities related to data access or modifications in the affected components.
🔍 How to Verify
Check if Vulnerable:
Check the Oracle E-Business Suite version and patch level; if running affected versions (12.1.1-12.1.3 or 12.2.3-12.2.10) without the April 2021 patches, it is vulnerable.Check Version:
Query the Oracle E-Business Suite database or application server for version details; e.g., use SQL queries or check configuration files specific to the installation.Verify Fix Applied:
Verify that patches from Oracle Critical Patch Update April 2021 have been applied by checking the patch history in Oracle E-Business Suite.📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests to Template or GTIN search endpoints, unexpected data modifications, or access by low-privileged users to sensitive functions.
Network Indicators:
- HTTP traffic to Oracle Product Hub ports from unauthorized sources, especially attempts to exploit known vulnerabilities.
SIEM Query:
Example: search for HTTP requests containing patterns related to Template or GTIN search in Oracle E-Business Suite logs, filtered by source IP and user privilege levels.
