🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploit details have been publicly disclosed on GitHub. SQL injection via Category parameter requires understanding of the application structure but uses common techniques.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: UNKNOWN

Vendor Advisory: https://phpgurukul.com/

Restart Required: No

Instructions:

No official patch available. Check vendor website for updates. Consider implementing input validation and parameterized queries as temporary fix.

🔧 Temporary Workarounds

Input Validation and Sanitization

PHP

Implement strict input validation for Category parameter to reject malicious SQL characters

Modify /edit-category.php to validate Category parameter using PHP filter functions or regex patterns

Web Application Firewall Rules

all

Deploy WAF rules to block SQL injection patterns targeting /edit-category.php

Add WAF rule: Block requests to /edit-category.php containing SQL keywords in Category parameter

🧯 If You Can't Patch

  • Isolate the e-Diary system behind a firewall with strict access controls
  • Implement database user with minimal privileges (read-only if possible) for the application

🔍 How to Verify

Check if Vulnerable:

Test /edit-category.php?id=8 with SQL injection payloads in Category parameter. Monitor for database errors or unexpected responses.

Check Version:

Check system documentation or about page. No standard version command available for this web application.

Verify Fix Applied:

Attempt SQL injection tests after implementing fixes. Verify no database errors or unauthorized data access occurs.

📡 Detection & Monitoring

Log Indicators:

  • Unusual database queries from web server
  • SQL syntax errors in application logs
  • Multiple failed login attempts following SQL injection patterns

Network Indicators:

  • HTTP requests to /edit-category.php with SQL keywords in parameters
  • Unusual database traffic patterns from web server

SIEM Query:

source="web_logs" AND uri="/edit-category.php" AND (param="Category" AND value MATCHES "(?i)(union|select|insert|delete|update|drop|--|#|;)")
