📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data exfiltration, authentication bypass, privilege escalation, and potential remote code execution via database functions.
Likely Case
Unauthorized access to sensitive bidding data, user credentials theft, and manipulation of auction/bidding records.
If Mitigated
Limited impact with proper input validation and WAF rules blocking SQL injection patterns.
🎯 Exploit Status
Exploit details are publicly available on GitHub and vuldb. SQL injection via login page is a well-understood attack vector.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameterized queries and input validation to /login.php to prevent SQL injection
Edit login.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $user);
Web Application Firewall Rules
allImplement WAF rules to block SQL injection patterns in login requests
ModSecurity rule: SecRule ARGS:User "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Implement network segmentation to isolate the bidding system from sensitive databases
- Deploy a reverse proxy with SQL injection filtering before the application
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads like: ' OR '1'='1 in the User parameterCheck Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Attempt SQL injection payloads and verify they are rejected or sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL-like patterns
- Successful logins from unexpected IPs
Network Indicators:
- HTTP POST requests to /login.php containing SQL keywords (UNION, SELECT, etc.)
- Abnormal response sizes from login endpoint
SIEM Query:
source="web_logs" AND uri="/login.php" AND (request LIKE "%UNION%" OR request LIKE "%SELECT%" OR request LIKE "%' OR '%'='%")
