Vulnerability Title
Asset directory traversal with some storage modules on Windows
Vulnerability Description
Wiki.js is a wiki app built on Node.js. Prior to version 2.5.254, directory traversal outside of Wiki.js context is possible when a storage module with local asset cache fetching is enabled on a Windows host. A malicious user can potentially read any file on the file system by crafting a special URL that allows for directory traversal. This is only possible on a Wiki.js server running on Windows, when a storage module implementing local asset cache (e.g Local File System or Git) is enabled and that no web application firewall solution (e.g. cloudflare) strips potentially malicious URLs. Commit number 414033de9dff66a327e3f3243234852f468a9d85 fixes this vulnerability by sanitizing the path before it is passed on to the storage module. The sanitization step removes any windows directory traversal sequences from the path. As a workaround, disable any storage module with local asset caching capabilities (Local File System, Git).

对路径名的限制不恰当(路径遍历)
Vulnerability Title
Wiki.js 路径遍历漏洞
Vulnerability Description
Wiki.js是Requarks.io团队的一套基于Node.js并使用JavaScript语言编写的开源Wiki软件。 Wiki.js 2.5.254 之前存在路径遍历漏洞，当在 Windows 主机上启用具有本地资产缓存获取的存储模块时，可以在 Wiki.js 上下文之外进行目录遍历。恶意用户可以通过制作允许目录遍历的特殊 URL 来潜在地读取文件系统上的任何文件。
