Question 1

What is Stored Cross-Site Scripting (XSS)?

Accepted Answer

What is Stored Cross-Site Scripting (XSS)?

Stored Cross-Site Scripting, or XSS, occurs when a malicious script is permanently stored on a target server, such as in a database, in a message forum, visitor log, comment field, or other location that allows input to be viewed by other users. When the malicious script is saved on the server, it will be delivered to all users who access the relevant feature, executing the script within the victim’s browser under the guise of the legitimate website. This makes it particularly dangerous as it can affect multiple users who simply access the infected page without any further action on their part.

Stored XSS can result in a variety of issues including stealing cookies, hijacking sessions, redirecting the victim to malicious websites, and more. The attacker gains the ability to perform any action that the user can perform, and to access any of the user’s data. If the user has privileged access within the application, this can compromise the entire application.

Question 2

How can I tell if my WordPress site has been affected by this vulnerability?

Accepted Answer

How can I tell if my WordPress site has been affected by this vulnerability?

To determine if your WordPress site has been affected by the Stored XSS vulnerability in ProfilePress, you should start by reviewing the version of the plugin you are currently using. If it is version 4.15.4 or earlier, your site is at risk or may already have been compromised. Check for unusual activity on your site, such as unexpected changes to website content, new administrative accounts you did not create, or reports from users about suspicious behavior.

You should also examine the site's logs for any signs of unauthorized access or unusual requests, particularly those involving the 'title' parameter used in the plugin. Additionally, employing a security plugin that scans for malware and signs of security breaches can help identify whether any malicious scripts have been injected into your site.

Question 3

What should I do if my site is compromised?

Accepted Answer

What should I do if my site is compromised?

If you discover that your site has been compromised, the first step is to clean the site of any malicious scripts or unauthorized changes. Reverting to a recent backup made before the compromise can be one of the quickest ways to restore your site to a safe state. Next, update the ProfilePress plugin to the latest version to patch the XSS vulnerability and prevent further exploits.

After securing your site, change all passwords, particularly for administrative accounts, and review user roles to ensure no unauthorized accounts have access. Implementing stricter security measures, such as two-factor authentication, can help protect your site moving forward. Lastly, inform your users about the breach, especially if their data may have been accessed or compromised.
