Resideo Plugin for Resideo – Real Estate WordPress Theme | Up to and including 2.5.4
How the Exploit Works
The vulnerability exists because the Resideo Plugin does not properly validate a user’s identity before updating their account details, such as their email address. An attacker with Subscriber-level access can exploit this flaw by changing the email address of any user, including administrators. The attacker can then initiate a password reset for the targeted account, which will be sent to the attacker-controlled email address. This allows the attacker to gain unauthorized access to the targeted account.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited:
POST /wp-admin/user-edit.php?user_id=[target_user_id] HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
Cookie: wordpress_logged_in_[hash]=[attacker_session]
email=[attacker_email]&pass1=[attacker_password]&pass2=[attacker_password]&action=updateIn this example, the attacker sends a POST request to the user-edit.php endpoint on the WordPress admin panel. The attacker uses their own authenticated session cookie (wordpress_logged_in_[hash]) and specifies the user_id of the targeted user. The email, pass1, and pass2 parameters are set to the attacker’s desired values, allowing the attacker to take control of the targeted account.
Mitigation Guidance
Users of the affected Resideo plugin are strongly urged to apply the vendor’s patch once it becomes available. In the meantime, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation, by blocking or alerting on suspicious activities related to the manipulation of user account details.
