CVE-2022-24606
📋 TL;DR
CVE-2022-24606 is a SQL injection vulnerability in Luocms v2.0 that allows attackers to execute arbitrary SQL commands through the /admin/news/sort_ok.php endpoint. This affects all Luocms v2.0 installations, potentially compromising the entire database and application. Attackers can steal, modify, or delete sensitive data including user credentials and system configurations.
💻 Affected Systems
- Luocms
📦 What is this software?
Luocms by Luocms Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, privilege escalation to admin, remote code execution via database functions, and full system takeover.
Likely Case
Database information disclosure, credential theft, data manipulation, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation, parameterized queries, and WAF protection blocking malicious SQL patterns.
🎯 Exploit Status
Exploitation requires admin authentication, but once authenticated, the SQL injection is straightforward to exploit. Public proof-of-concept code is available in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch exists. Recommended action is to upgrade to a newer version of Luocms if available, or implement workarounds and consider migrating to alternative CMS solutions.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd input validation and parameterized queries to the sort_ok.php file to prevent SQL injection.
Edit /admin/news/sort_ok.php to replace raw SQL queries with prepared statements using PDO or mysqli
Access Restriction
linuxRestrict access to the vulnerable endpoint using web server configuration or application-level controls.
Add .htaccess rules to block access to /admin/news/sort_ok.php or implement IP whitelisting
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block SQL injection patterns targeting the vulnerable endpoint
- Disable or remove the vulnerable sort_ok.php file and implement alternative sorting functionality
🔍 How to Verify
Check if Vulnerable:
Check if Luocms version is 2.0 and examine /admin/news/sort_ok.php for unsanitized SQL queries using user input.Check Version:
Check Luocms configuration files or database for version information, typically in config files or admin panelVerify Fix Applied:
Test the sort_ok.php endpoint with SQL injection payloads to confirm they are properly blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by access to sort_ok.php
- SQL error messages containing injection payloads
Network Indicators:
- HTTP POST requests to /admin/news/sort_ok.php containing SQL keywords like UNION, SELECT, INSERT
SIEM Query:
source="web_logs" AND (url="/admin/news/sort_ok.php" AND (request_body CONTAINS "UNION" OR request_body CONTAINS "SELECT" OR request_body CONTAINS "INSERT"))
