WordPress is the most prominent content management system in the world. Like many other web development frameworks, WordPress is open-source, and anyone can expand its functionality with custom plugins and themes. WordPress developers and users can simply opt for WordPress plugins if they wish to increase the performance of their website with third-party extensions. Since June 2021, the market share of sites using WordPress has grown to about 42% of all major sites. As WordPress continues to grow, more hackers are targeting sites created with WordPress.
Currently, more security researchers are analyzing WordPress-based software than ever before,
Including plugins and themes, for exposure. This also makes the WordPress ecosystem very safe.
The most common vulnerability is Cross-Site Scripting which accounts for more than 36.2% of total vulnerabilities, SQL Injection counts 9.1% risk and Cross-Site Request Forgery comes third with a 6.5% interruption. To find out the vulnerabilities originated from third parties, which are harder than those found in the WordPress core. What makes matters worse is that most popular plugins have millions of active plugins and the numbers are not good considering how many websites affected plugins are compromised.
One of the most common methods used by threatening attackers is to compromise WordPress site password attacks. Taking advantage of widespread password reuse on various sites, threatening attackers targeting WordPress sites usually uses a list of suspended passwords to try to access the site. Described as a “credential stuffing attack,” these attacks are often more effective because of people resorting to compromised passwords on all sites.
Another common password attack feature that threatens actors to use to target WordPress sites is dictionary attacks. In this case, the attackers used a dictionary to guess the password. In addition, hybrid attacks that use a combination of dictionary attacks and powerful attack methods are popular. This password attack is usually successful due to people using weak passwords that contain dictionary words with little difficulty.
1. Directory Traversal :
Directory Traversal vulnerability occurs when an unauthorized user can access files outside the target and perform an action such as downloading, reading, or deleting a file. More often than not, attackers try to use these types of disabilities to read or delete the / wp-config.php file.
2. SQL Injection :
This type of vulnerability occurs when additional SQL commands or queries can be assigned to an existing query for more information in the database. This vulnerability may be the second number on our list due to the large number of applications it can take to determine if a site is compromised and is successfully extracted information from the database.
3. Local File Inclusion :
The risk of local file installs occurs when locally managed files can be added to the page to generate code or display file contents. Attackers repeatedly try to find ways to learn and download sensitive files, so it’s not surprising to see this close to the top of the list.
4. Cross Site Scripting(XSS) :
This is one of the most common problems in the WordPress ecosystem. It is easy to introduce the vulnerability of the XSS. In an XSS malicious scripts are injected into trusted websites. This helps the attacker to execute malicious scripts, resulting in hijacking user sessions or redirecting the user to untrusted sites.
5. Malicious File Uploads :
The risk of file uploads is often the victim of threatening actors who consider the greatest impact they can have on the affected site. If the attacker can upload a PHP file to the WordPress site, where they can create conflicting commands that allow for continuous site infection.
