Jul 3, 2023

A critical unpatched security vulnerability in the popular Ultimate Member plugin has left over 200,000 WordPress websites vulnerable to malicious attacks. The exploit targets the plugin's ability to create new user accounts, and allows attackers to create secret admin accounts with full control over compromised websites.

The vulnerability, known as CVE-2023-3460, affects all versions of the Ultimate Member plugin, including the latest release (version 2.6. 6). It has been actively exploited by hackers, who have been using it to create secret admin accounts on vulnerable websites.

How the vulnerability works

The vulnerability exists in the way that the Ultimate Member plugin handles user registration requests. When a user registers for a new account, the plugin sends a request to the WordPress database to create a new user record. However, the plugin does not properly validate the values that are sent in the request. This means that an attacker can manipulate the request to create a new user account with any role, including the administrator role.

How to exploit the vulnerability

To exploit the vulnerability, an attacker simply needs to visit a vulnerable website and click on a malicious link. This will trigger the vulnerability, and the attacker will be able to create a new user account with administrative privileges.

The malicious link will typically be disguised as a legitimate link, such as a link to a news article or a product page. However, when the link is clicked, it will actually redirect the user to a malicious website that is controlled by the attacker.

Once the user arrives at the malicious website, the attacker will be able to steal the user's cookies, which will allow them to log in to the user's account. The attacker can then use the account to gain full control over the website.

How to protect your site

If you are using the Ultimate Member plugin, it is critical that you update to the latest version as soon as possible. You can also disable the plugin until a patch is released.

In addition to updating the Ultimate Member plugin, there are a few other things you can do to protect your WordPress site from attack:

• Use strong passwords for all of your user accounts.

• Keep your WordPress software up to date.

• Install a security plugin.

• Be careful about what links you click on.

By following these simple steps, you can help to protect your WordPress site from attack.
