📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or full system takeover via SQL injection to RCE chaining.
Likely Case
Unauthorized access to sensitive client data, database manipulation, or potential privilege escalation.
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.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates or apply workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd proper input validation and parameterized queries to /user_void_transaction.php
Edit PHP file to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE order_id = ?'); $stmt->bind_param('s', $order_id);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns
Add WAF rule: SecRule ARGS:order_id "@detectSQLi" "id:1001,deny,status:403"
🧯 If You Can't Patch
- Restrict network access to the application using firewall rules
- Implement database user with minimal required permissions
🔍 How to Verify
Check if Vulnerable:
Check if /user_void_transaction.php exists and contains unsanitized order_id parameter usageCheck Version:
Check application version in admin panel or readme filesVerify Fix Applied:
Test with SQL injection payloads like ' OR '1'='1 in order_id parameter📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application
Network Indicators:
- HTTP requests to /user_void_transaction.php with SQL keywords in parameters
SIEM Query:
source="web.log" AND uri="/user_void_transaction.php" AND (order_id="*'*" OR order_id="*SELECT*" OR order_id="*UNION*")
