📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, authentication bypass, and potential remote code execution via database functions.
Likely Case
Unauthorized data access, privilege escalation, and potential administrative account takeover.
If Mitigated
Limited impact with proper input validation and database permissions, though SQL injection attempts would still be logged.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily exploitable by attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify admin.php to implement proper input validation and use prepared statements for database queries.
Edit admin.php to replace direct SQL concatenation with parameterized queries using PDO or mysqli prepared statements.
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the userid parameter.
Configure WAF to block requests containing SQL keywords in userid parameter: UNION, SELECT, INSERT, UPDATE, DELETE, DROP, etc.
🧯 If You Can't Patch
- Isolate the application behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test by sending SQL injection payloads to the userid parameter in admin.php requests and observing database errors or unexpected responses.Check Version:
Check software version in application interface or configuration files.Verify Fix Applied:
Attempt SQL injection tests and verify they are blocked or sanitized without affecting legitimate functionality.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in application logs
- Unusual database queries from admin.php
- Multiple failed login attempts via admin interface
Network Indicators:
- HTTP requests to admin.php with SQL keywords in parameters
- Unusual database port traffic from web server
SIEM Query:
source="web_logs" AND uri="*admin.php*" AND (param="*userid*UNION*" OR param="*userid*SELECT*" OR param="*userid*OR*1=1*")
