What is the Bricks Theme Builder vulnerability?
Theme information
- Vulnerable theme version: 1.9.6 and earlier
- Patch release version: 1.9.6.1 and newer
About the vulnerability
Bricks is one of the most popular theme builders in the WordPress ecosystem. It boasts of the ability to add custom code (CSS, JS, HTML, PHP) to various parts of a website, which gives users much more control when it comes to customizing their sites.
The Bricks Theme Builder vulnerability stems from the improper usage of the eval() function. It allows arbitrary PHP code to be executed, which is why using it is dangerous. This function was used in many distinct methods within the plugin code, of which render_element() was the most significant one. This method is used to display previews within the custom code editor and could be used by attackers to insert malicious code into vulnerable websites and mount RCE attacks. What’s even more scary is that no privilege or expertise is required to exploit this vulnerability and hack a site. Consequently, this vulnerability has been assigned a CVSS score of 9.8 (Critical).
Meanwhile, Patchstack has reported that they are aware of a malware that exploits this vulnerability. They also believe that this malware can disable security plugins like Wordfence and Sucuri.
The vulnerability has now been fixed with the release of Bricks Theme Builder v1.9.6.1 on February 13, 2024.
Who discovered this vulnerability?
The vulnerability in the Bricks Theme Builder was discovered by researchers at Snicco, who informed the developer bricksbuilder.io on February 10, 2024. Subsequently, the developer released a patch on February 13, 2024, followed by a full disclosure of the vulnerability on February 19, 2024.
How is your WordPress site at risk?
If your WordPress site is running Bricks Theme Builder version 1.6.9 or anything older, it’s time to sit up and take notice. You’re wide open to Remote Code Execution (RCE) attacks, and trust us, you don’t want that. RCE attacks let hackers put their own malicious code onto your site from miles away, claim the throne by becoming admins, and basically have a field day doing harm.
Here’s a scary thought: What if a hacker decides to drop a piece of code on your site that’s like a secret agent, sneaking a peek at the data passing between your site’s server and your visitors? That’s not just a privacy nightmare waiting to happen but could also make people think twice about visiting your site again. And to add insult to injury, while the hacker’s code is doing its sneaky business, it could slow your site down to a crawl. That means unhappy visitors, plummeting Google rankings, and a whole lot of headaches for you.
But wait, it gets worse. If a hacker gets their hands full-on access to your site, here’s the kind of chaos they could unleash:
- They could turn your site into a zombie, attacking other sites and possibly getting you blacklisted by Google.
- Imagine your site getting hijacked to mine cryptocurrency, slowing it down, or even knocking it offline.
- Your users could start getting bombarded with spam or phishing emails, and that’s a surefire way to lose trust.
- Or picture this: your visitors are suddenly redirected to, well, let’s just say unsavory websites.
- Hackers might leave a backdoor open, so they can waltz back in any time they like, even after you’ve fixed the initial problem.
- Worst case scenario, they could trash your site so badly that you’d be left picking up the pieces, hoping you have a recent backup to restore from.
So, your agenda is crystal clear: address this security loophole right now! It’s about protecting your site as well as safeguarding your reputation and your visitors’ trust.
