📦 What is this software?
Luocms by Luocms Project
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the CMS with administrative privileges, allowing data theft, website defacement, malware injection, and potential lateral movement to connected systems.
Likely Case
Unauthorized administrative access leading to website defacement, data exfiltration, and installation of backdoors for persistent access.
If Mitigated
Limited impact if proper network segmentation, WAF rules, and input validation are implemented, though vulnerability remains exploitable.
🎯 Exploit Status
SQL injection in login page allows authentication bypass without credentials. Simple payloads can be used to gain admin access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative CMS or implementing custom fixes with parameterized queries and input validation.
🔧 Temporary Workarounds
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting /admin/login.php
# Example ModSecurity rule: SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Cloudflare WAF: Enable SQLi protection rules
Admin Interface Restriction
allRestrict access to /admin/ directory to specific IP addresses only
# Apache: Order deny,allow
Deny from all
Allow from 192.168.1.0/24
# Nginx: allow 192.168.1.0/24;
deny all;
# .htaccess: Require ip 192.168.1.0/24
🧯 If You Can't Patch
- Implement network-level restrictions to limit access to admin interface to trusted IPs only
- Deploy a web application firewall with SQL injection detection rules specifically for /admin/login.php
🔍 How to Verify
Check if Vulnerable:
Test /admin/login.php endpoint with SQL injection payloads like ' OR '1'='1 in username/password fields. Monitor for successful authentication bypass.Check Version:
Check Luocms version in admin panel or look for version indicators in source code/composer filesVerify Fix Applied:
Attempt SQL injection payloads against /admin/login.php and verify they are rejected or properly sanitized without allowing unauthorized access.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts followed by successful login from same IP
- Admin login from unexpected IP addresses or user agents
Network Indicators:
- HTTP POST requests to /admin/login.php containing SQL keywords (UNION, SELECT, OR, etc.)
- Rapid authentication attempts with varying payloads
SIEM Query:
source="web_logs" AND uri="/admin/login.php" AND (request_body LIKE "%OR%" OR request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%")
