📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, authentication bypass, and potential server takeover via SQL injection to RCE escalation.
Likely Case
Unauthorized access to student records, grade manipulation, credential theft, and potential privilege escalation within the portal.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or partial data exposure.
🎯 Exploit Status
SQL injection via Username parameter requires no authentication. Public proof-of-concept exists in GitHub repository.

✅ 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 Filter
allAdd input validation to sanitize Username parameter before processing
Modify /check_user.php to implement parameterized queries or input sanitization
Web Application Firewall Rule
allBlock SQL injection patterns in Username parameter
Add WAF rule to detect and block SQL injection attempts on /check_user.php
🧯 If You Can't Patch
- Implement network segmentation to restrict access to the portal
- Deploy a web application firewall with SQL injection detection rules
🔍 How to Verify
Check if Vulnerable:
Test /check_user.php with SQL injection payloads in Username parameter (e.g., ' OR '1'='1)Check Version:
Check portal version in admin interface or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error messages📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application
- Multiple failed login attempts with SQL patterns
Network Indicators:
- HTTP POST requests to /check_user.php containing SQL keywords
- Unusual database traffic patterns
SIEM Query:
source="web_logs" AND uri="/check_user.php" AND (payload CONTAINS "UNION" OR payload CONTAINS "SELECT" OR payload CONTAINS "OR '1'='1")
