Xibo 是一个开源的数字标牌平台，包含基于 Web 的内容管理系统和 Windows 显示播放器软件。在 4.4.3 版本之前， 中缺少对权限（Authorization）的校验，导致拥有“模块查看”权限的用户能够查看（而非修改）仅限超级管理员访问的模块设置，并泄露完整的模块实体信息。该漏洞可被任何拥有“模块查看”权限的授权用户利用；该权限默认并不授予非管理员用户。建议用户升级至 4.4.3 版本以修复此问题，升级至修复版本是必要的缓解措施。若无法升级的用户，应从不受信任的用户处撤销相应权限。

Vulnerability Title
Xibo CMS Missing Authorization in Module::settingsForm due to PHP operator precedence
Source: CVE Program / CVE List V5
Vulnerability Description
Xibo is an open source digital signage platform with a web content management system and Windows display player software. Prior to 4.4.3, missing Authorization in Module::settingsForm allows to view (not change) super admin-restricted module settings and leak the full module entity. Exploitation of the vulnerability is possible on behalf of an authorized user who has access to the Module View feature, which are not granted to non-admins as standard. Users should upgrade to version 4.4.3 which fixes this issue. Upgrading to a fixed version is necessary to remediate. Users unable to upgrade should revoke such privileges from users they do not trust.
