📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including database takeover, credential theft, data exfiltration, and potential lateral movement to other systems.
Likely Case
Authentication bypass leading to unauthorized system access, data leakage of user/courier information, and potential privilege escalation.
If Mitigated
Limited impact with proper input validation and WAF rules blocking malicious SQL patterns.
🎯 Exploit Status
Public disclosure available via GitHub references; SQL injection typically requires minimal technical skill to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement parameterized queries or prepared statements in /ajax.php to prevent SQL injection.
Modify PHP code to use PDO or mysqli with prepared statements for email parameter
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting /ajax.php endpoint.
Add WAF rule: Block requests to /ajax.php containing SQL keywords in email parameter
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from application servers
🔍 How to Verify
Check if Vulnerable:
Test /ajax.php endpoint with SQL injection payloads in email parameter (e.g., ' OR '1'='1)Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL patterns
- Unexpected database queries from /ajax.php
Network Indicators:
- HTTP POST requests to /ajax.php containing SQL keywords
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/ajax.php" AND (email="*OR*" OR email="*UNION*" OR email="*SELECT*")
