🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://github.com/thedigicraft/Atom.CMS/issues/255
Restart Required: No
Instructions:
1. Review the GitHub issue for community patches. 2. Manually implement parameterized queries in /admin/login.php. 3. Validate and sanitize all user inputs.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection rules to block malicious requests.
Input Validation
allImplement strict input validation for login parameters.
🧯 If You Can't Patch
- Isolate the AtomCMS instance behind a reverse proxy with strict filtering.
- Implement network segmentation to limit database access from the web server.
🔍 How to Verify
Check if Vulnerable:
Test the /admin/login.php endpoint with SQL injection payloads like ' OR '1'='1.Check Version:
Check the AtomCMS version in the admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection payloads no longer work and login functionality remains intact.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple failed login attempts with SQL-like patterns
- Successful admin logins from unexpected IPs
Network Indicators:
- HTTP POST requests to /admin/login.php containing SQL keywords
- Unusual database query patterns from the web server
SIEM Query:
source="web_logs" AND uri="/admin/login.php" AND (message="sql" OR message="union" OR message="select")
