Input Validation Web Application Firewall Rule
allBlock login requests with empty username or password parameters at the WAF level
WAF specific - configure rule to block POST requests to login endpoint with empty username or password parameters
Temporary Authentication Hardening
allAdd server-side validation to check for empty credentials before processing
Modify application code to validate username and password are not empty before authentication logic
🧯 If You Can't Patch
- Implement network-level restrictions to limit access to the CRM login page to trusted IP addresses only
- Enable multi-factor authentication if supported, though this may not fully mitigate the bypass
