Description
Summary
The GeoWebCache home page includes version and revision information about the software in use. This information is sensitive from a security point of view because it allows software used by the server to be easily identified.
Details
org.geowebcache.GeoWebCacheDispatcher.handleFrontPage(HttpServletRequest, HttpServletResponse) has no check to hide potentially sensitive information from users except for a hidden system property to hide the storage locations that defaults to showing the locations.
PoC
Just open http://localhost:8080/geoserver/gwc/
Impact
In addition to exposing the version and revision information, the home page will expose the config file and storage locations which may expose the system's temp directory location and whether or not GeoServer is running in a Windows operating system. The approximate server start time and some basic GWC usage information is also exposed.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
