FileRise 是一款自托管的基于 Web 的文件管理器，支持多文件上传、编辑和批量操作。在 3.16.0 版本之前，当管理员启用了 WebDAV 功能时，FileRise 的 WebDAV 基本身份认证仅通过 方法验证账户的用户名和密码，而未强制要求提供账户已配置的两步验证（TOTP）因素。攻击者若知晓启用 TOTP 的账户的有效主凭据（用户名和密码），即可在未提供第二因素的情况下成功认证到已启用的 WebDAV 服务，并利用该账户的 WebDAV 文件权限。虽然浏览器登录路径会强制实施 TOTP 验证，但独立

Vulnerability Title
FileRise: WebDAV authentication bypasses TOTP/MFA entirely
Source: CVE Program / CVE List V5
Vulnerability Description
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, when an administrator has enabled WebDAV, FileRise WebDAV Basic authentication validates only the account username and password through AuthModel::authenticate() and does not enforce the account's configured TOTP factor. An attacker who knows valid primary credentials for a TOTP-enabled account can authenticate to the enabled WebDAV service without supplying the second factor and exercise the account's WebDAV file permissions. The browser login path enforces TOTP, but the separate public/webdav.php authentication callback did not. This issue is fixed in version 3.16.0.
