- Isolate DocSys instance behind network segmentation with strict access controls
- Implement database-level protections: minimal privileges, query logging, and regular audit trails
🔍 How to Verify
Check if Vulnerable:
Check DocSys version in admin interface or configuration files. If version ≤ 2.02.36, system is vulnerable.Check Version:
Check web interface or configuration files for version informationVerify Fix Applied:
Test search functionality with SQL injection payloads (e.g., ' OR '1'='1) and verify they are rejected or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from DocSys application
- SQL syntax errors in application logs
- Multiple failed login attempts via search functionality
Network Indicators:
- HTTP requests with SQL keywords in searchWord parameter
- Unusual database connection patterns from application server
SIEM Query:
source="DocSys" AND (searchWord CONTAINS "UNION" OR searchWord CONTAINS "SELECT" OR searchWord CONTAINS "OR '1'='1")🔗 References
