WPBookit Plugin for WordPress | Up to and including 1.0.2
How the Exploit Works
The WPBookit plugin fails to properly validate a user’s identity prior to updating their account details through the edit_profile_data() function. This flaw allows an unauthenticated attacker to modify arbitrary user’s email addresses and passwords, including those of administrators. With these new credentials, the attacker can then gain unauthorized access to the user’s account, potentially leading to a full system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited:
POST /wpbookit/edit_profile_data HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"user_id": "admin_user",
"new_email": "attacker@example.com",
"new_password": "attacker_password"
}In this example, the attacker sends a POST request to the ‘edit_profile_data’ endpoint of the WPBookit plugin. The ‘user_id’ is set to ‘admin_user’, and the ‘new_email’ and ‘new_password’ fields are filled with the attacker’s chosen details. If successful, the attacker would then have full access to the ‘admin_user’ account.
Mitigation Guidance
As immediate steps to mitigate this vulnerability, users are advised to either apply the vendor patch or use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary solution. It is also recommended to always monitor your systems for unusual activity and ensure that your software is up-to-date with the latest security patches.
