⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise allowing data exfiltration, privilege escalation, or system takeover via SQL injection leading to remote code execution.
Likely Case
Unauthorized data access, modification, or deletion of database contents including sensitive user information or system configuration.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, restricting SQL injection attempts.
🎯 Exploit Status
SQL injection via RID parameter is well-documented and easy to exploit with standard SQLi techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Check for official patch from MRCMS developers. 2. If available, download and apply patch. 3. Test functionality after patching.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for RID parameter to only accept numeric values
Modify /admin/article/delete.do to validate RID parameter as integer before processing
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns
Configure WAF to detect and block SQL injection attempts on /admin/article/delete.do
🧯 If You Can't Patch
- Restrict access to admin interface using network segmentation and firewall rules
- Implement strong authentication and monitor admin account activity for suspicious behavior
🔍 How to Verify
Check if Vulnerable:
Test /admin/article/delete.do endpoint with SQL injection payloads in RID parameter (e.g., 1' OR '1'='1)Check Version:
Check MRCMS version in admin panel or configuration filesVerify Fix Applied:
Test with same SQL injection payloads after fix - should return error or no database interaction📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed delete attempts with malformed RID parameters
- Admin panel access from unexpected IPs
Network Indicators:
- HTTP requests to /admin/article/delete.do with SQL injection patterns in parameters
SIEM Query:
source="web_logs" AND uri="/admin/article/delete.do" AND (param="RID" AND value MATCH "[';]|OR|UNION|SELECT")
