📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential server takeover via SQL injection to RCE chaining.
Likely Case
Authentication bypass allowing unauthorized admin access, data exfiltration of member information, and potential database manipulation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation preventing database access.
🎯 Exploit Status
Public exploit available on GitHub, simple SQL injection requiring minimal technical skill
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates 2. Apply any available patches 3. Test authentication functionality
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize Username parameter before processing
Modify check_admin.php to include parameterized queries or input sanitization
Web Application Firewall
allDeploy WAF with SQL injection protection rules
Configure WAF to block SQL injection patterns at /intern/admin/check_admin.php
🧯 If You Can't Patch
- Block external access to /intern/admin/ directory via firewall or web server configuration
- Implement network segmentation to isolate the database server from web application layer
🔍 How to Verify
Check if Vulnerable:
Test the Username parameter with SQL injection payloads like ' OR '1'='1 at /intern/admin/check_admin.phpCheck Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer bypass authentication or return database errors📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in Username parameter logs
- Multiple failed login attempts with SQL patterns
- Successful admin logins from unexpected IPs
Network Indicators:
- HTTP POST requests to /intern/admin/check_admin.php containing SQL keywords
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri="/intern/admin/check_admin.php" AND (Username="*OR*" OR Username="*UNION*" OR Username="*SELECT*")
