🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: https://github.com/chilin89117/ED01-CMS/issues/4

Restart Required: No

Instructions:

1. Check if you're running ED01-CMS v20180505. 2. Consider migrating to a maintained CMS. 3. Apply input validation fixes to post.php if continuing to use this version.

🔧 Temporary Workarounds

Input Validation for post.php

all

Add parameterized queries or input sanitization to the vulnerable post.php component

# Modify post.php to use prepared statements instead of direct SQL concatenation
# Example for PHP/MySQLi: $stmt = $conn->prepare('SELECT * FROM posts WHERE id = ?'); $stmt->bind_param('i', $id);

Web Application Firewall (WAF)

all

Deploy a WAF with SQL injection protection rules

# Configure WAF to block SQL injection patterns
# Example ModSecurity rule: SecRule ARGS "@detectSQLi" "id:1234,phase:2,deny"

🧯 If You Can't Patch

  • Isolate the CMS system from sensitive networks and databases
  • Implement strict network access controls and monitor all database queries

🔍 How to Verify

Check if Vulnerable:

Check if ED01-CMS version is 20180505 by examining version files or configuration. Test post.php endpoint with SQL injection payloads.

Check Version:

grep -r '20180505' /path/to/ed01-cms/ or check version.php/config.php files

Verify Fix Applied:

Test the post.php endpoint with SQL injection payloads after applying fixes. Verify no database errors or unexpected behavior occurs.

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple failed login attempts via post.php
  • Unexpected database queries from web server

Network Indicators:

  • SQL keywords in HTTP POST requests to post.php
  • Unusual database connection patterns

SIEM Query:

source="web_logs" AND uri="/post.php" AND (message="SQL" OR message="syntax" OR message="database")
