The most important WordPress vulnerabilities to be aware of are Arbitrary file uploads and SQL injection.
What vulnerabilities in WordPress are being targeted?
When hacking WordPress, hackers use a haphazard method of hitting the easiest and most likely vulnerabilities it has on the site.
Because WordPress is the world’s most popular CMS, with over 100 million sites, there are tools available to hack into multiple WordPress sites one after another to try to find the most prominent vulnerabilities.
The two most easily exploitable vulnerabilities that hackers can exploit are arbitrary file uploads and SQL injections.
What are Arbitrary file uploads and SQL injection?
Arbitrary file uploads are vulnerabilities (link to vulnerability database) that allow arbitrary file uploads.
Hackers often use this vulnerability as a starting point to install backdoors that allow them to alter files on the server, change WordPress settings to make it impossible to log in to the administration panel, or embed malicious code in the site content.
SQL injection is a vulnerability (link to vulnerability database) that may allow the database to be rewritten. This one is less targeted than Arbitrary file uploads, but if an easily exploitable vulnerability is discovered, hackers may launch an intensive attack.
There is an epidemic of hacker attacks.
When Arbitrary file uploads or SQL injections are discovered in plug-ins with high penetration, an epidemic occurs in which the vulnerability is widely used.
As mentioned above, hackers use tools to attack these vulnerabilities by obtaining a huge number of WordPress listings from search engines, etc. It does not matter how small your site is, as long as it is listed on a search engine, sooner or later it will be exposed to hackers’ vulnerability attacks. It does not matter how small your site is, as long as it is listed on a search engine, it will sooner or later be exposed to hacker vulnerability attacks.
In our experience, if a vulnerability is left unchecked, it is likely to be caught in a hacker’s net within six months to a year.
It is important to stay on top of vulnerabilities!
If you run WordPress, we recommend that all sites on your server be tested for vulnerabilities every few months.
