Explaining the Gravity Forms Vulnerability for Small Business Owners

/ Web Marketing / By

If you’re a small business owner using WordPress for your website, this vulnerability in the Gravity Forms plugin could be a serious concern for you. Let’s break it down in plain terms and explain what it means, why it’s dangerous, and what you can do to protect your business.

What is Gravity Forms?

Gravity Forms is a popular plugin for WordPress that allows users to create custom forms, such as contact forms, order forms, or surveys, without needing technical expertise. It’s widely used by businesses because it’s easy to set up and customize.

What is the Problem?

A vulnerability has been discovered in versions 2.9.1.3 and earlier of the Gravity Forms plugin. The issue involves something called Stored Cross-Site Scripting (XSS).

Here’s what happens:

  1. Gravity Forms has an option for adding images to your forms, and you can give these images alternative text (known as the “alt” attribute).
  2. Due to insufficient checks on what text is entered in the “alt” attribute, hackers can inject malicious scripts instead of regular text.
  3. Once injected, these scripts are stored on your website’s server. When you or your visitors access the page containing the malicious script, it executes automatically.

Why is This Dangerous?

  • Unauthenticated Attackers: This means hackers don’t even need to log in to your website. They can exploit this vulnerability from the outside.
  • Stored Attacks: The malicious code remains on your site until it’s removed, affecting all users who visit the compromised page.
  • What Hackers Can Do:
    • Steal sensitive user data (like form submissions or login details).
    • Redirect visitors to harmful or phishing websites.
    • Damage your website’s reputation by showing inappropriate or harmful content to visitors.
    • Reduce customer trust, which can harm your business financially.

What Does “High Severity” Mean?

The CVSS score for this vulnerability is 7.2 out of 10, meaning it is considered a high-severity issue. This rating reflects how easy it is to exploit and the potential damage it can cause.

  • AV:N: The attack can be done over the internet.
  • AC:L: It’s easy for an attacker to exploit.
  • PR:N: No privileges (like logging in) are needed to attack.
  • UI:N: It doesn’t require any action by a user (like clicking a link).

What Should Small Business Owners Do?

Here’s a step-by-step guide to protect your website and business:

1. Check Your Plugin Version

  • Log into your WordPress dashboard.
  • Go to Plugins > Installed Plugins.
  • Find Gravity Forms and check the version number. If it’s 2.9.1.3 or earlier, you’re vulnerable.

2. Update Gravity Forms

  • Visit the Gravity Forms website or check your WordPress plugin updates.
  • Install the latest version of the plugin. Updates usually contain security fixes.

3. Apply a Web Application Firewall (WAF)

  • Tools like Cloudflare or Wordfence can block common attack patterns and keep your site safer.

4. Sanitize Inputs

  • If you have a developer, ensure they check all inputs on your site (like form fields) to prevent similar vulnerabilities.

5. Backup Your Website

  • Regularly back up your website using tools like UpdraftPlus or Jetpack. If something goes wrong, you can restore your site to a previous state.

6. Monitor Website Security

  • Use a security plugin (like Sucuri or Wordfence) to scan for vulnerabilities and monitor unusual activity on your site.

7. Educate Yourself

  • Stay informed about WordPress vulnerabilities by subscribing to newsletters or using tools like WPScan.

What Happens If You Don’t Act?

Ignoring this issue can lead to:

  • Loss of Customer Trust: A compromised site damages your brand’s reputation.
  • Legal Risks: If sensitive user data is stolen, you could face lawsuits or regulatory fines.
  • Revenue Loss: A hacked site can reduce traffic, sales, or lead to downtime.

Conclusion

As a small business owner, your website is critical to your success. This vulnerability in Gravity Forms is a reminder of the importance of keeping plugins and your site secure. By taking the steps outlined above, you can reduce the risk and keep your business and customers safe.
