Summary
GeoServer Missing Authorization on REST API Index
Details

Summary

It is possible to bypass the default REST API security and access the index page.

Details

The REST API security handles rest and its subpaths but not rest with an extension (e.g., rest.html).

Impact

The REST API index can disclose whether certain extensions are installed.

Workaround

In ${GEOSERVER_DATA_DIR}/security/config.xml, change the paths for the rest filter to /rest.*,/rest/** and change the paths for the gwc filter to /gwc/rest.*,/gwc/rest/** and restart GeoServer.
