Summary
Directory exposure in jetty
Details

Impact

If the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink (soft link in Linux), the contents of the ${jetty.base}/webapps directory may be deployed as a static web application, exposing the content of the directory for download.

For example, the problem manifests in the following ${jetty.base}: ```$ tree demo-base/ demo-base/ ├── etc ├── lib ├── resources ├── start.d ├── deploy │   └── async-rest.war └── webapps -> deploy

```

Workarounds

Do not use a symlink

Severity
2.7 (Low)
