🛠️ 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
allAdd 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)
allDeploy 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.
