What the vulnerability does

01Description

The DesignThemes LMS plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.0.4. This is due to the 'dtlms_register_user_front_end' function not restricting what user roles a user can register with. This makes it possible for unauthenticated attackers to supply the 'administrator' role during registration and gain administrator access to the site.

DesignThemes LMS versions 1.0.4 and earlier contain a privilege management flaw that allows unauthenticated attackers to gain full control over the system.
