How to Stop XML-RPC Attack in WordPress

WordPress utilizes XML-RPC to remotely execute functions for example JetPack, WordPress mobile application etc.  But XMLRPC Attack made web server jam. In HTTP access log, we saw a lot of requests like this:

61.135.232.103 - - [11/Sep/2020:10:27:20 -0500] "POST /xmlrpc.php HTTP/1.1" 200 401 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0"
91.132.142.57 - - [11/Sep/2020:10:39:03 -0500] "POST /xmlrpc.php HTTP/1.1" 200 401 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0"
5.33.187.36 - - [11/Sep/2020:10:43:28 -0500] "POST /xmlrpc.php HTTP/1.1" 200 401 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0"

You will also get “Error connecting to database” message when your WordPress site is down.

Solutions

We can secure server from XMLRPC attacks in several ways

  • We can add a HTTP directive to httpd.conf or .htaccess for denying all requests on /xmlrpc.php.
    <files xmlrpc.php>
      Order allow,deny
      Deny from all
    </files>

    If don’t have httpd.conf or .htaccess, we can simply rename the filename.

    • Where is httpd.conf?
      /etc/httpd/conf/httpd.conf
    • DirectAdmin: File Editor
    • Webmin: Others > File Manager
  • Installing the Jetpack Plugin can block the XML-RPC requests with its “Protect” function.
