🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Vendor did not respond to disclosure. Consider upgrading if vendor releases fix or implement workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for Username parameter to reject SQL special characters
Implement parameterized queries or prepared statements in UserMapper.xml
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns in Username parameter
Configure WAF to detect and block SQL injection patterns in POST/GET parameters
🧯 If You Can't Patch
- Isolate DocSys instance behind firewall with strict network access controls
- Implement database user with minimal permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Check if DocSys version is 2.02.37 or earlier. Test Username parameter with SQL injection payloads like ' OR '1'='1Check Version:
Check application version in DocSys interface or configuration filesVerify Fix Applied:
Test with SQL injection payloads after implementing parameterized queries or input validation📡 Detection & Monitoring
Log Indicators:
