🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor vendor for official patch. 2. Consider upgrading to latest version if available. 3. Apply workarounds immediately.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation for the 'tag' parameter in api_controller.php
Modify /include/controller/api_controller.php to sanitize tag parameter input
WAF Rule
allImplement web application firewall rules to block SQL injection patterns
Add WAF rule: Detect and block SQL injection attempts on tag parameter
🧯 If You Can't Patch
- Restrict access to /include/controller/api_controller.php via web server configuration
- Implement network segmentation to isolate Emlog Pro instances from sensitive systems
🔍 How to Verify
Check if Vulnerable:
Check if /include/controller/api_controller.php exists and contains vulnerable code for tag parameter handling.Check Version:
Check Emlog Pro version in admin panel or via version file.Verify Fix Applied:
Test SQL injection attempts against the tag parameter to confirm they are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts after SQL injection attempts
- Unexpected parameter values in web server logs for tag parameter
Network Indicators:
- SQL injection payloads in HTTP requests to api_controller.php
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/include/controller/api_controller.php" AND (tag CONTAINS "'" OR tag CONTAINS "--" OR tag CONTAINS "UNION")
