Original NVD Description

GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. In version 3.3.22, the password reset endpoint can be accessed without authentication. When a reset request is submitted for an existing user, the application generates a new temporary password and immediately stores its hash as the user's new password. The temporary password is generated using PHP rand() seeded with microtime(). Because this seed is time-based and has a limited effective search space, an attacker can generate possible reset password candidates. Since the admin login endpoint does not enforce rate limiting or account lockout, these candidates can be tested online until the correct password is found. Successful exploitation may lead to administrator account takeover. At time of publication, there are no publicly available patches.
