Apply official patches
Immediately download and install the latest security updates provided by JoomShaper for SP Page Builder to address the underlying unauthenticated file upload vulnerability.
Update affected systems
Ensure that all instances of SP Page Builder are updated to version 6.6.2 or later. Audit all Joomla environments to identify and upgrade any installations running vulnerable versions.
Restrict access
Implement Web Application Firewall (WAF) rules to block unauthorized POST requests to SP Page Builder upload endpoints and restrict access to the Joomla administrative interface to trusted IP addresses.
Monitor for exploitation
Conduct a forensic review of web directories for unauthorized PHP files, especially in media or upload folders, and monitor web server logs for suspicious unauthenticated file upload attempts.
Detection Guidance
"Monitor web server access logs for unusual POST requests targeting SP Page Builder components, specifically looking for unauthenticated traffic. Security teams should search for the presence of unexpected .php files within image or media upload directories. Deploying WAF signatures to detect arbitrary file upload patterns and auditing Joomla logs for unauthorized configuration changes can help identify potential exploitation attempts associated with this critical vulnerability."
