中文标题:
FileBrowser 安全漏洞
英文标题:
File Browser vulnerable to Username Enumeration via Timing Attack in /api/login
漏洞描述
中文描述:
FileBrowser是Seagate开源的一款网页文件浏览器。提供指定目录下的文件管理界面，可用于上传、删除、预览、重命名和编辑您的文件。它允许创建多个用户，每个用户可以有自己的目录。它可以用作独立的应用程序或中间件。 FileBrowser 2.55.0之前版本存在安全漏洞，该漏洞源于JSONAuth.Auth函数存在逻辑缺陷，可能导致未经验证的攻击者通过测量/api/login端点的响应时间来枚举有效用户名。
英文描述:
File Browser provides a file managing interface within a specified directory and can be used to upload, delete, preview, rename, and edit files. Prior to version 2.55.0, the JSONAuth. Auth function contains a logic flaw that allows unauthenticated attackers to enumerate valid usernames by measuring the response time of the /api/login endpoint. The vulnerability exists due to a "short-circuit" evaluation in the authentication logic. When a username is not found in the database, the function returns immediately. However, if the username does exist, the code proceeds to verify the password using bcrypt (users.CheckPwd), which is a computationally expensive operation designed to be slow. This difference in execution path creates a measurable timing discrepancy. Version 2.55.0 contains a patch for the issue.
