📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, modification, deletion, or potential remote code execution if database functions allow it.
Likely Case
Unauthorized data access, privilege escalation, and potential administrative account takeover.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-critical data.
🎯 Exploit Status
Exploit details are publicly disclosed on GitHub, making weaponization straightforward for attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://itsourcecode.com/
Restart Required: No
Instructions:
No official patch available. Check vendor website for updates. Consider migrating to alternative software if no fix is provided.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize registration_id parameter before processing
Modify /ajax.php to validate registration_id as integer using: if(!is_numeric($_POST['registration_id'])) { die('Invalid input'); }
Web Application Firewall Rule
allBlock SQL injection patterns targeting /ajax.php?action=save_payment endpoint
WAF rule: deny requests to /ajax.php?action=save_payment containing SQL keywords in parameters
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls, allowing only trusted IP addresses
- Implement database-level protections: use least-privilege database accounts, enable query logging, and regularly audit database activity
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted request to /ajax.php?action=save_payment with SQL injection payload in registration_id parameter and observing database errors or unexpected behavior.Check Version:
Check software version in admin panel or review source code headers/comments for version 1.0 referencesVerify Fix Applied:
After implementing workarounds, test with the same SQL injection payloads to confirm they are blocked or sanitized properly.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs for /ajax.php
- Multiple rapid requests to save_payment endpoint with varying registration_id values
- Database queries containing UNION, SELECT, or other SQL keywords from web application
Network Indicators:
- HTTP POST requests to /ajax.php?action=save_payment with SQL syntax in parameters
- Unusual database connection patterns from web server IP
SIEM Query:
source="web_logs" AND url="/ajax.php" AND action="save_payment" AND (registration_id CONTAINS "'" OR registration_id CONTAINS "UNION" OR registration_id CONTAINS "SELECT")
