What the vulnerability does
01Description
The CRM Memberships plugin for WordPress is vulnerable to privilege escalation via password reset in all versions up to, and including, 2.6. This is due to missing authorization and authentication checks on the `ntzcrm_changepassword` AJAX action. This makes it possible for unauthenticated attackers to reset arbitrary user passwords and gain unauthorized access to user accounts via the `ntzcrm_changepassword` endpoint, granted they can obtain or enumerate a target user's email address. The plugin also exposes the `ntzcrm_get_users` endpoint without authentication, allowing attackers to enumerate subscriber email addresses, facilitating the exploitation of the password reset vulnerability.
Explanation of Vulnerability in Simple Terms
02Summary
CRM Memberships versions 2.6 and earlier lack proper authorization checks, allowing unauthenticated attackers to read, modify, or delete data without logging in. The vulnerability affects all core functions of the application. Site administrators should update immediately to a version newer than 2.6.
