Fast Food Ordering System by Fast Food Ordering System Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including theft of sensitive data (customer information, payment details, admin credentials), data destruction, or full system takeover via privilege escalation.
Likely Case
Unauthorized data access including customer records, order history, and potentially admin credentials stored in the database.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data reading from specific tables.
🎯 Exploit Status
Public proof-of-concept exists in GitHub repository. Exploitation requires no authentication and uses simple SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify receipt.php to use prepared statements with parameterized queries instead of direct string concatenation
Replace vulnerable code with: $stmt = $conn->prepare('SELECT * FROM sales WHERE id = ?'); $stmt->bind_param('i', $_GET['id']); $stmt->execute();
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns targeting the vulnerable endpoint
ModSecurity rule: SecRule ARGS_GET:id "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the admin interface to trusted IP addresses only
- Deploy a web application firewall (WAF) with SQL injection detection rules in front of the application
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payload: /ffos/admin/sales/receipt.php?id=1' OR '1'='1Check Version:
Check PHP files for version comments or look at application interface footerVerify Fix Applied:
Test with same payload after fix - should return error page or no data instead of executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple requests to receipt.php with special characters in id parameter
- Database query errors containing user input
Network Indicators:
- HTTP requests to /ffos/admin/sales/receipt.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri_path="/ffos/admin/sales/receipt.php" AND (param_id CONTAINS "'" OR param_id CONTAINS "OR" OR param_id CONTAINS "UNION")
