GeoServer Missing Authorization on REST API Index
🔗 CVE IDs covered (1)
📋 Description
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.
