📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution through database functions.
Likely Case
Database information disclosure, privilege escalation, and unauthorized access to sensitive content management system data.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit requires access to admin interface, but SQL injection can potentially bypass authentication. Public exploit code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None
Vendor Advisory: None
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative CMS solutions or implementing custom fixes with proper input validation.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation for the id parameter to only accept expected values and sanitize SQL queries.
Modify admin/admin_process.php to add parameter validation and use prepared statements
Access Restriction
allRestrict access to admin interface using IP whitelisting or additional authentication layers.
Add .htaccess rules to restrict admin directory access
Implement IP-based access controls in web server configuration
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns targeting the id parameter
- Isolate the CMS instance in a segmented network with strict outbound traffic controls
🔍 How to Verify
Check if Vulnerable:
Test the admin/admin_process.php endpoint with SQL injection payloads in the id parameter (e.g., id=1' OR '1'='1).Check Version:
Check CMS version in admin panel or look for version information in source files.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return appropriate error messages or are blocked.📡 Detection & Monitoring
