Description

This module adds a form on the password-reset-landing page to allow changing the password of the user during the log in process.

The module does not sufficiently validate all access tokens, which allows an attacker to change the password of any arbitrary user and gain access to their account.

In order to exploit, the attacker must have an active account on the site.
