WordPress plugin needs to be saved against zero-day vulnerability

Wordpress PluginAny type of vulnerability in any software comes with so many difficulties that the software developer needs to be extra careful everytime he comes up with a new piece of software. This time we are talking about nothing else but a WordPress plugin and how it’s threats can become a dangerous sight in the future if you don’t take care of the same. After all, no developer wants to create a fuss in the life of those who uses his product or software for sure.

In this article, we will be talking about the zero-day vulnerability that triggered a WordPress Plugin ust anytime. We considered giving you a fresh example and how it robbed off the security form the WordPress website users in the worst possible manner.

We can’t decline the fact that a software should always be safe to use or integrate into the website but it is kind of a vulnerability that is seen as a loophole by the hacker and that the software developer feels that it is quite difficult to give the solution to that particular bug or loophole in the WordPress plugin. We can definitely say that he is the incharge of the software and he should look to it if the product can expose the website to any potential or open-ended dangers as no one would love him for that.

What actually is zero-day vulnerability?

Before we leap to the concept straight away, let us begin by the fact that you know well about the software vulnerability. After all, the level 2 of software vulnerability goes on to become zero-day vulnerability!

Cyber world or in simple terms- our favorite internet world is replete with so many insecurities from so many aspects that one or the other drawback is targeted by the hackers. These should generally be not left unaddressed as they pose bigger threats in the future for all the website visitors on the website with integrated WordPress plugin and now we can move on to explain why these are called zero-day vulnerability?

The difference between a normal software threat and the former is that the flaw or the error in programming is known to the software developer but unfortunately he is not able to give a cover/ or a patch to that error or to fix or mend it.

In this case, we can say that the flaw will be left untreated and thus, exposes the website to the dangers of the hackers or cyber criminals or attackers. It is definitely the weakness of a website that further leads to disappointment and anxiety for the website owner.

Risks associated with zero-day vulnerability are:

Firstly, the hackers detect what they have to create more loopholes into the already existing ones. Then, they are masterminds and really apt in coding just to inject malwares and infections into the software so that when the user clicks or takes any action related to the website, their browsing activity is affected or they are simply facing hurdles and confusing activities happening on the website. The extreme level hacking is known to infect the whole PC of the website user.

Did you know that after much hard work, the software developers can fix the zero-day vulnerabilities easily but they are still not 100% secure for the people as the vendor stops thinking about the risks and the hijackers take the advantage.

Latest hijacking into the WordPress plugin is as following:

This vulnerability affects WP GDPR compatibility. A WordPress plugin that helps website owners comply with the GDPR standard. This plugin is one of the most popular GDPR theme plugins in the WordPress directory as there are already over 100k downloads of the same. About a month ago, one attacker found a vulnerability in the plugin when using the WordPress website and installing the backdoor script. The first report about the hacked site came in a support forum for another plugin, but the plugin was eventually installed on the second stage of the hacked site.

Then the WordPress security team conducted a survey, due to which all came to know that the cause of hacking is from WP GDPR Compliance, a common plug-in installed on all ill-fated affected sites. A couple weeks ago, when WordPress team found certain security issues in the code, the only solution that they were left with was to remove the plugin completely from the directory so that no one is able to use that plugin into the WordPress website. This plugin returned into the WordPress plugin directory just a more than a couple days ago, but only after version 1.4.3 was released, whose author included the issue to be corrected for the reported problem.

Can we consider that the safe zone has started?

Well, unfortunately, here is a big no regarding the safety of using the same plugins. As it has already been confirmed by the experts in the WordPress field that the attack is still in progress and that of course will cross the cover ups or the fix-ups in the way. A defiant security expert who uses the Wordfence firewall extension for WordPress said that despite these fixes, attacks on sites that are still running on 1.4.2 or earlier are running as it was in the past. Company analysts say they are still looking for attacks that attempt to exploit one of the reported WP GDPR compliance issues.

Especially since an attacker targets WP GDPR compliant errors, you can call the plugin’s internal function to change the configuration, but this also applies to the entire WordPress CMS. The Wordfence team said he had two types of attacks that exploit this vulnerability. The first case is this:

  1. Hackers use bugs to open the site’s user registration system.
  2. Hackers use bugs to set the default value for new accounts for the administrator.
  3. Hacker automatically registers a new account as an administrator.
  4. Hackers set the default role of new accounts as “subscribers”.
  5. Hackers block general user registration.
  6. Hackers log into a new administrator account.
  7. Then they install the back port on the web site called wp – cache.php.

According to WordPress, this backdoor script (see below) includes a file manager, a terminal emulator, and an eval () function channel for PHP, “According to such a script on this site, You can expand the payload.”

Conclusion:

However, experts found another type of attack in a WordPress plugin. This is not dependent on creating a new administrator account that the hacked site owner can find. Another starting point is to add a new task to WP-Cron (WordPress’s built-in task designer) with the WP GDPR Compliance error in quiet technology.
