4 WordPress Vulnerabilities You Need to Fix

How secure is your WordPress site?

Your answer will usually be “I don’t know” or “I didn’t know, I needed security” WordPress is a secure platform as long as security measures are put in place and updated regularly. 

Usage statistics of content management system research shows that WordPress is being used by 36% of all websites and 63% use WordPress as a content management system. By looking at those statistics WordPress vulnerabilities are almost inevitable if users and developers aren’t careful and vigilant about a WordPress breach. Hackers look for insecure setups, outdated system versions and vulnerable plugins and themes as well.

We also want to emphasize that WordPress vulnerabilities are far beyond WordPress core setup, this means themes, plugins also play an enormous role when it comes to publishing your website live on the internet. WordPress Vulnerability Statistics by wpvulndb.com recent report of 18,306 vulnerabilities in their database breaks it down to percentages:

  • 20% of WordPress plugins are vulnerable
  • 78% From the core of WordPress
  • 2% Are from WordPress themes

1) Remote File Inclusion Vulnerability (RFI)
This action may vary on the execution of permissions that your server grants to the user. This means if vulnerable code is used to remotely load data into your site, an attacker can find a way to gain access to your website; making it possible to inject code that leads to concerns such as divulgence of information depending on the type of site or content that your website might have. This can be prevented; one of your website’s most important files is wp-config.php, and keeping it secure and having its security settings locked or hiding its location can decrease the chances of being hacked.

2) Script Injections
WordPress runs on a MySQL database and SQL injections will occur if a hacker gains access to your WordPress database and all of your data. These types of hacks can lead to malicious links and spam inserted into your website and can potentially lead to your domain being blacklisted; making sure strong passwords are being used (at least 12 characters) and your website host needs to be a reliable server and that alone can decrease the chances of an attack.

3) Malware or “Malicious Software”
Malicious Software is a code that helps hackers gain access to your website and gather sensitive information. A breached WordPress site is when malware has been injected into your website core files. The hacker would scan your website for vulnerabilities such as old versions of WordPress, though there are many types of malware and WordPress isn’t vulnerable to all of them, the most Common WordPress Malware Infections are:

  • Backdoors
  • Poor user access management
  • Soup-kitchen servers
  • Out-of-date software
  • Corner-cutting

You can prevent this by locking down your core files, limiting access by default, and enabling two-factor authentication. We recommend using Google Authentication; an app that generates codes for you to log-in to your site; every 10-15 seconds the app will generate a brand new code for you to use. You can also fix these issues by restoring your websites back-up and making sure it’s a version that isn’t infected. Always have a backup strategy in place when unpredictable situations transpire. 

4) Soup-kitchen Shared Servers
We all know there are many low-cost web hosting out there, these are most commonly known as shared hosting; they offer cheap deals and poor quality service. Your WordPress resides on these servers, and hackers prefer to target and attack low-maintenance and low-quality web hosting. These types of servers are whats making your site vulnerable to an attack. This can become a huge pain point because shared hosting means that they have multiple sites being hosted in a single server. If one of those websites is breached, a hacker can or will be able to access other sites and potentially their database. On the other hand, private servers can be more expensive but the reassurance of having your site hosted on its server adds a layer of security.
