⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution via database functions.
Likely Case
Unauthorized access to sensitive restaurant data (customer information, financial records, employee data), privilege escalation, and potential system takeover.
If Mitigated
Limited data exposure if database permissions are properly restricted and input validation is implemented elsewhere.
🎯 Exploit Status
Exploit requires admin access to reach /admin/user_save.php, but SQL injection is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes with parameterized queries.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize username/name parameters before processing
Modify /admin/user_save.php to implement parameterized queries or input sanitization
Access Restriction
allRestrict access to /admin/user_save.php file
Add .htaccess rules to restrict IP access or implement additional authentication
🧯 If You Can't Patch
- Implement web application firewall (WAF) with SQL injection rules
- Restrict database user permissions to minimum required
🔍 How to Verify
Check if Vulnerable:
Check if /admin/user_save.php exists and test username parameter with SQL injection payloads like ' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test the same SQL injection payloads after implementing fixes to confirm they're blocked📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple failed login attempts followed by SQL-like strings in requests
Network Indicators:
- HTTP POST requests to /admin/user_save.php containing SQL keywords (UNION, SELECT, INSERT, etc.)
SIEM Query:
source="web_server" AND (url="/admin/user_save.php" AND (request_body CONTAINS "UNION" OR request_body CONTAINS "SELECT" OR request_body CONTAINS "' OR"))
