⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, authentication bypass, privilege escalation, and potential remote code execution on the underlying server.
Likely Case
Authentication bypass allowing unauthorized access to the management system, followed by data exfiltration or manipulation of parcel tracking and customer information.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing successful exploitation.
🎯 Exploit Status
Exploitation requires no authentication and is straightforward due to direct SQL injection in login parameter. Public proof-of-concept code exists in GitHub repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
1. Replace vulnerable login.php with secure version using parameterized queries. 2. Implement input validation for all user inputs. 3. Consider upgrading to a newer version if available from the vendor.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns in login requests
Input Sanitization Patch
allManually patch login.php to sanitize username parameter before SQL query
Replace vulnerable SQL query with prepared statements using mysqli or PDO
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the web server
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads in username field (e.g., admin' OR '1'='1)Check Version:
Check system version in admin panel or review source code for version markersVerify Fix Applied:
Attempt SQL injection after patching to confirm payloads are rejected or properly escaped📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login attempts
- Multiple failed login attempts with SQL characters
- Successful logins from unexpected IPs
Network Indicators:
- SQL keywords in HTTP POST parameters to login.php
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri="/login.php" AND (request_body LIKE "%' OR '%" OR request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%")
