WPGYM – WordPress Gym Management System | Up to and including 67.7.0
How the Exploit Works
The vulnerability stems from a lack of validation on a user-controlled key in the ‘MJ_gmgt_gmgt_add_user’ function of the WPGYM plugin. Attackers with mere subscriber-level access can exploit this flaw by manipulating this key, allowing them to change the email, password, and other details of any user, including those with administrator privileges.
Conceptual Example Code
The following pseudocode illustrates how an attacker might exploit this vulnerability:
POST /wp-admin/admin-ajax.php?action=MJ_gmgt_gmgt_add_user HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
user_id=<ADMIN_USER_ID>&email=<ATTACKER_EMAIL>&password=<ATTACKER_PASSWORD>&role=administratorIn this example, the attacker changes the email and password of an administrator-level user, potentially granting them full control over the victim’s WordPress site.
Mitigation and Recommendations
It is essential that users of the affected WPGYM – WordPress Gym Management System plugin promptly apply the vendor’s patch to fix this vulnerability. For temporary mitigation, users may employ Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS). However, these are not permanent solutions and can only offer limited protection. The most effective defense against this exploit is to update the plugin as soon as a patch is available.
