📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to theft of customer PII, financial data, and reservation records, potential ransomware deployment, and full system takeover.
Likely Case
Data exfiltration of customer information, modification of reservation records, and potential privilege escalation to administrative access.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or partial data exposure.
🎯 Exploit Status
Exploit details are publicly available on GitHub, making this easily weaponizable by attackers.
🛠️ 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 Sanitization
allImplement strict input validation and parameterized queries for the Name parameter in edit_query_account.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE name = ?'); $stmt->bind_param('s', $name);
Web Application Firewall (WAF)
allDeploy WAF rules to block SQL injection patterns targeting the vulnerable endpoint
Add WAF rule: Block requests containing SQL keywords (UNION, SELECT, INSERT, etc.) in POST parameters to /admin/edit_query_account.php
🧯 If You Can't Patch
- Block external access to /admin/edit_query_account.php using firewall rules or .htaccess restrictions
- Implement network segmentation to isolate the reservation system from sensitive databases
🔍 How to Verify
Check if Vulnerable:
Test the /admin/edit_query_account.php endpoint with SQL injection payloads in the Name parameterCheck Version:
Check system documentation or configuration files for version informationVerify Fix Applied:
Attempt SQL injection after implementing parameterized queries and verify no database errors or unexpected behavior📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts to admin interface
- Unexpected database queries from web server
Network Indicators:
- HTTP POST requests to /admin/edit_query_account.php containing SQL keywords
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/admin/edit_query_account.php" AND (payload="UNION" OR payload="SELECT" OR payload="INSERT")
