Patch Version: Unknown

Vendor Advisory: https://code-projects.org/

Restart Required: No

Instructions:

1. Check vendor website for updates. 2. If no patch available, implement workarounds. 3. Consider replacing with alternative software.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Add parameterized queries or input validation to login.php

Modify login.php to use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE username = ?'); $stmt->bind_param('s', $username);

Web Application Firewall

all

Deploy WAF with SQL injection protection rules

🧯 If You Can't Patch

  • Isolate the system behind a firewall with strict access controls
  • Implement network segmentation to limit database access

🔍 How to Verify

Check if Vulnerable:

Test login.php with SQL injection payloads like ' OR '1'='1 in Username field

Check Version:

Check software documentation or admin panel for version information

Verify Fix Applied:

Attempt SQL injection after implementing fixes; should return proper error or no database interaction

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple failed login attempts with SQL syntax

Network Indicators:

  • HTTP requests to login.php containing SQL keywords (UNION, SELECT, INSERT)

SIEM Query:

source="web_logs" AND uri="/login.php" AND (request CONTAINS "UNION" OR request CONTAINS "SELECT" OR request CONTAINS "INSERT")
