}

Implement Web Application Firewall (WAF)

all

Configure WAF rules to block authentication bypass attempts

# ModSecurity rule example
SecRule REQUEST_URI "@contains userregister.php" \
    "id:1001,phase:1,deny,status:403,msg:'CVE-2022-1084 Block'"

🧯 If You Can't Patch

  • Implement network segmentation to isolate the vulnerable system from critical networks
  • Enable detailed logging and monitoring for authentication bypass attempts

🔍 How to Verify

Check if Vulnerable:

Check if /one_church/userregister.php exists and is accessible via web browser or curl command

Check Version:

Check application files or database for version information, typically in config files or footer

Verify Fix Applied:

Attempt to access the userregister.php file and verify it returns 403 or is inaccessible

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed authentication attempts followed by successful login from same IP
  • Access to userregister.php with unusual parameters
  • User accounts created/modified without proper authentication logs

Network Indicators:

  • HTTP requests to /one_church/userregister.php with authentication bypass parameters
  • Unusual traffic patterns to authentication endpoints

SIEM Query:

source="web_server" AND (uri="/one_church/userregister.php" OR uri CONTAINS "userregister") AND (status=200 OR status=302)
