Technical details
The vulnerability is a missing authorization check in the Module::settingsForm method, stemming from a PHP operator precedence issue. An attacker who is an authorized user with the Module View privilege (not granted to non-admins by default) can bypass authorization checks to view (but not modify) super-admin-restricted module settings and access the full module entity. The attack vector is network-based with low complexity, requiring low-level privileges (a Module View role) and no user interaction. The impact is limited to confidentiality disclosure of module configuration data. The fix is available in version 4.4.3.
