📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database takeover leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow it.
Likely Case
Unauthorized data extraction including user credentials, bidding information, financial data, and system configuration.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permissions restricting dangerous operations.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub and vuldb. Attack requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check code-projects.org for security updates. 2. If no patch available, implement workarounds. 3. Consider migrating to alternative software if vendor support is unavailable.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize ID parameter before processing
// In details.php, add before SQL query:
$id = filter_var($_GET['ID'], FILTER_VALIDATE_INT);
if ($id === false) { die('Invalid ID'); }
Web Application Firewall Rule
linuxBlock SQL injection patterns in ID parameter
# ModSecurity rule:
SecRule ARGS:ID "(?i:(union|select|insert|update|delete|drop|exec|xp_))" \
"id:1001,phase:2,deny,status:403,msg:'SQL Injection Attempt'"
# Apache .htaccess:
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|exec|xp_) [NC]
RewriteRule .* - [F,L]
🧯 If You Can't Patch
- Implement network segmentation to isolate the bidding system from critical databases
- Deploy a web application firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Test /details.php with SQL injection payload: /details.php?ID=1' OR '1'='1Check Version:
Check source code for version information or review installation documentationVerify Fix Applied:
Test with same payload after fixes; should return error or sanitized response instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple requests to /details.php with special characters in ID parameter
- Database query errors containing SQL syntax
Network Indicators:
- HTTP requests with SQL keywords in ID parameter
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/details.php" AND (query="*union*" OR query="*select*" OR query="*' OR '*" OR query="*--*" OR query="*;*" OR query="*sleep(*")
