Classpath resource disclosure in GWC Web Resource API on Windows / Tomcat

GeoServer is an open source server that allows users to share and edit geospatial data. Prior to versions 2.23.5 and 2.24.3, if GeoServer is deployed in the Windows operating system using an Apache Tomcat web application server, it is possible to bypass existing input validation in the GeoWebCache ByteStreamController class and read arbitrary classpath resources with specific file name extensions. If GeoServer is also deployed as a web archive using the data directory embedded in the `geoserver.war` file (rather than an external data directory), it will likely be possible to read specific resources to gain administrator privileges. However, it is very unlikely that production environments will be using the embedded data directory since, depending on how GeoServer is deployed, it will be erased and re-installed (which would also reset to the default password) either every time the server restarts or every time a new GeoServer WAR is installed and is therefore difficult to maintain. An external data directory will always be used if GeoServer is running in standalone mode (via an installer or a binary). Versions 2.23.5 and 2.24.3 contain a patch for the issue. Some workarounds are available. One may change from a Windows environment to a Linux environment; or change from Apache Tomcat to Jetty application server. One may also disable anonymous access to the embeded GeoWebCache administration and status pages.

对路径名的限制不恰当(路径遍历)

GeoServer 安全漏洞

GeoServer是一个用 Java 编写的开源软件服务器。允许用户共享和编辑地理空间数据。 GeoServer 存在安全漏洞，该漏洞源于如果使用 Apache Tomcat Web 应用服务器将 GeoServer 部署在 Windows 操作系统中，则可以绕过 GeoWebCache ByteStreamController 类中现有的输入验证并读取具有特定文件扩展名的任意类路径资源。
