🔧 Temporary Workarounds

Disable file uploads

all

Restrict file upload functionality in WordPress or at web server level

# In .htaccess for Apache: 
<FilesMatch "\.(php|phtml|php3|php4|php5|php7|phps|php8|inc|pl|py|jsp|asp|aspx|sh|cgi|exe)$">
    Order Allow,Deny
    Deny from all
</FilesMatch>
# In nginx config:
location ~ \.(php|phtml|php3|php4|php5|php7|phps|php8|inc|pl|py|jsp|asp|aspx|sh|cgi|exe)$ {
    deny all;
}

Implement file type validation

all

Add server-side validation to restrict uploads to safe file types only

# PHP example validation:
$allowed_types = ['jpg', 'jpeg', 'png', 'gif', 'pdf'];
$file_extension = strtolower(pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION));
if (!in_array($file_extension, $allowed_types)) {
    die('Invalid file type');
}

🧯 If You Can't Patch

  • Switch to a different WordPress theme immediately
  • Implement web application firewall (WAF) rules to block suspicious file uploads

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel > Appearance > Themes for Wiguard theme version. If version is below 2.0.1, system is vulnerable.

Check Version:

# In WordPress installation directory:
grep -r "Version:" wp-content/themes/wiguard/style.css

Verify Fix Applied:

Confirm Wiguard theme version is 2.0.1 or higher in WordPress admin panel. Test file upload functionality with malicious file types to ensure they are rejected.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file uploads to theme directories
  • POST requests with file uploads to unexpected endpoints
  • Execution of PHP files from upload directories

Network Indicators:

  • HTTP POST requests with file uploads to theme-related endpoints
  • Subsequent connections to uploaded web shells

SIEM Query:

source="web_server" (method="POST" AND uri="*upload*" AND (file_extension="php" OR file_extension="phtml" OR file_extension="jsp"))
