🔍 How to Verify
Check if Vulnerable:
Check if IBM i2 Intelligent Analysis Platform version is 9.2.1; review system logs for crash events related to document processing.Check Version:
Check application version via the product's interface or installation logs; on Windows, use 'wmic product get name,version' or similar system commands.Verify Fix Applied:
Verify the patch is applied by checking the version against the patched release in IBM's advisory and testing with safe documents.📡 Detection & Monitoring
Log Indicators:
- Application crashes or unexpected termination logs when opening documents
- Unusual process creation or network connections from the i2 process
Network Indicators:
- Outbound connections to suspicious IPs from the i2 application
- Anomalous document downloads or file transfers
SIEM Query:
Example: 'source="i2_logs" AND (event_type="crash" OR process_name="malicious.exe")'
