WordPress Plugins : Wonders or Blunders

A warning has been issued by security researchers that around 10,000 websites that are on WordPress CMS are vulnerable because of a plugin that has a zero-day flaw.  For this, we have WP Mobile Detector plugin which can be said as the source of the issue, and this also contains a zero-day vulnerability that was also discovered by the Plugin Vulnerabilities team.

Wherein looking at the current stature of WordPress we know that the  WordPress plugin development services has made the platform a highly extendable one and have proven to be the sole reason behind the perpetual success of the platform. This brings to us the moot question that whether plugins are good for a website or not. Now that we already know that WP plugins do offer a great deal of extendability to our websites, here we will discuss that whether the benefits offered by the plugins are worth the trade-off with the vulnerability they produce.

How Do Plugins Make Your Website Vulnerable?

One of the most asked questions to skilled WordPress developers about plugins  is : How do plugins they contribute to the vulnerability of your website?   So the answer to this question is that the plugins often have an obsolete code, as this is quite difficult for the developers to consistently update them along with every official WordPress release. Moreover, they might also consist of slow code and add shortcuts that open gaps in the security. Missing security elements in plugins can open your website to everything from SQL injections to cross-site scripting assaults.

Caveat! Top Plugins Can Also Be Hacked

There is no guarantee to the fact that the most popular plugins are the most reliable ones. There is no cure to hacking despite the fact that it was being installed by an ample lot of users. For instance, we have a brilliant plugin called Yoast SEO and Google Analytics by Yoast, which is widely used by the users. Last year an XSS vulnerability was discovered by the Joost de Valk, who also happens to be the creator of the plugin itself.

He learned the fact that the arguments such as add_query_arg as well as remove_query_arg, are not properly implemented in the plugins, wherefore this can become a reason to exploit it via cross-site scripting (XSS).

Dynamic web pages come under the influence of XSS. When you are not able to escape the content properly, then it makes the string interpret it as the code. This gives a room to the hacker to add a malicious code and even instill in the website  several problems that can cripple the system, this can also be including acquiring the login details of the users, intervening the website’s content, and also adding a phishing code which is capable of transmitting confidential data to malicious users.

It was further noticed that popular plugins such as  Gravity Forms, Jetpack, and even plugins such as All In One SEO pack also had some codes that could create problems.

Off late some serious issues were discovered within Jetpack, which happens to be a popular plug-in, using which you can optimize your website for free, get proper security features and other things. This plugin was developed by Automatic, and this also happens to be the company that fuels WordPress.com as well as the WordPress open-source project and manages over a million active installations.

A renowned Web security organization Sucuri released a report stating that the all the Jetpack release ever since 2012, commencing with version 2.0 are facing stored cross-site scripting (XSS) vulnerability.
