Top 7 Common WordPress Security Exploits/Vulnerabilities

 


There are a lot of websites that use WordPress for their website needs, because it is a popular Content Management System. The WordPress Security Exploits/Vulnerabilities have evolved over the years. All security articles can be found on the WordPress.org website.

If you are aware of these security vulnerabilities, these can be crossed off your list of hacks. Follow the steps to fix these WordPress vulnerabilities.

Prefix for database tables by default

As part of the installation process, you will be asked to enter the database prefix for the tables. Most WordPress beginners will install WordPress with the “wp_” table prefix. There is a major security risk for your WordPress website because you have made a lot of guesswork easy for hackers. They can access your WordPress users table directly, as well as other important tables like the posts table.

By changing the table prefix from “wp_” to something else of your choice, you will secure your WordPress site.

Account for the default administrator

You must enter the WordPress Admin login credentials when installing WordPress. Your website is more vulnerable to being hacked if you have created an administrator account with “admin.”.

What happens if you are using an “admin” account is that it will become easier to guess the username of your website. A hacker can work directly on cracking the password for your WordPress website. You just reduced the hacker’s workload by half. You can easily fix this if you are still using the “admin” account.

Create a new account with administrator privileges to fix this issue. Log into the new account and reduce the privileges of the “admin” account or delete it entirely.

Login attempts made with brute force

By repeatedly inserting usernames and password combinations on a website, hackers attempt to gain access to its login credentials using brute force attacks. And the bad news is that it’s an automated attack, so the hacker doesn’t have to enter the username and password manually every time.

If there are multiple failed login attempts, WordPress won’t limit the number of logins. So the hacker can try n number of attempts until he succeeds or your website goes down because of completely using the resources and bandwidth. If you are using shared hosting, this will affect your website.

Limit the number of login attempts if a user has failed multiple times. You can use the Loginizer plugin free of charge.

SQL Injection in WordPress

WordPress is based on PHP, an extremely popular server-side language, and all the data will be stored in MySQL, including content, pages, and users. The language used to communicate with databases is SQL. WordPress is not an exception when it comes to SQL Injections. Additionally, WordPress is vulnerable to SQL Injection attacks.

Assign the proper privileges to the database user to stop SQL Injection attacks. Make sure the configuration files have the correct permissions. Update the plugins, themes, and WordPress core files. In SQL Injections, several factors are involved, such as whether the server’s Database version is current. You cannot do anything about it if you have shared hosting.

Files that are sensitive are accessible

WordPress websites have a number of important files, such as wp-config.php and install.php. It is highly recommended that you do not allow anyone else to access the wp-config.php file since it contains all WordPress configuration details. Changing the default 755 to 644 will make it harder for anyone to access it.

You can check the file permissions using plugins, or else you can log into cPanel and open file manager, change the directory permissions to 755 and all file permissions to 644. Your WordPress website will no longer be able to access sensitive files after you make this change.

XSS (cross-site scripting)

Cross-Site Scripting attacks are most commonly used to steal data from website visitors or to redirect them to another site. By injecting javascript code onto specific pages of your website, XSS attackers capture data from your users and send it to them.

Whenever you enable any user-generated data, such as comments, attackers will inject JavaScript code. You can allow limited tags such as italic, bold, and underline within these comments. If you allow additional tags, then your website may be vulnerable to Cross-Site Scripting attacks.

Malware

Malware is malicious software injected into your website files. The attacker can use this malicious code to perform any operation on your website, including erasing all the data on your website. This is a lot of malware, but if you follow the above steps then you won’t have to worry about them.

When you open your website on Chrome or in a search engine like Google, you will see a notice if your website contains this malware.

Summary

You have eliminated a lot of problems on your website by following the tips above. Those issues can be resolved by following the steps. In the comment section below, please let me know of any WordPress Security Exploits or Vulnerabilities that I may have missed.
