CVE-2023-46608 is a critical vulnerability that affects the WPDo DoLogin Security plugin, which is widely used by webmasters and bloggers to enhance their WordPress site's security. The security plugin has a flaw, specifically a missing authorization vulnerability, which leaves it open to exploits by attackers who can bypass the security levels. The vulnerability allows attackers to take advantage of incorrectly configured access control security levels to gain unauthorized access to the website. This issue affects all DoLogin Security versions from n/a through 3.7.1.

Exploit Details

The missing authorization vulnerability in DoLogin Security lies in the access control security levels' configuration. When incorrect configuration is present, it is possible for an attacker to bypass these security levels and gain unauthorized access to sensitive data or privileged functionality. The exploit would work as follows:

1. An attacker sends a crafted HTTP request with specific parameters targeting the vulnerable DoLogin Security plugin.

2. The targeted plugin checks the provided parameters to determine the appropriate access level for the requester.

3. Due to the missing authorization vulnerability, the plugin fails to verify if the user should have the requested access level or not. Instead, it grants the requested access based on the provided parameters.

4. The attacker is granted unauthorized access to the sensitive data or functionality, enabling them to carry out malicious activities, such as database manipulation, defacement of the site, or stealing user credentials.

An example of the exploit in action is as follows

import requests

target_url = 'http://example.com';  # Replace with the target WordPress site URL
dologin_security_url = f'{target_url}/wp-content/plugins/dologin_security?param1=xxx&param2=yyy'
response = requests.get(dologin_security_url)

if response.status_code == 200:
    print("Exploit successful!")
    # Perform any additional malicious activities here
else:
    print("Exploit failed. The site might not be vulnerable or is using a patched version of DoLogin Security.")

In order to protect your WordPress site from this vulnerability, you should take the following steps

1. Ensure your DoLogin Security plugin is updated to the latest version (3.7.1) to fix the vulnerability.

2. Regularly review and update your access control security levels' configuration, making sure they are correctly set up to provide the appropriate level of access to your site's various user roles.

3. Monitor your site's logs for any suspicious activity, such as unauthorized access or unexpected changes.
