GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A path traversal vulnerability in versions 2.23.4 and prior requires GeoServer Administrator with access to the admin console to misconfigure the Global Settings for log file location to an arbitrary location. The admin console GeoServer Logs page provides a preview of these contents. As this issue requires GeoServer administrators access, often representing a trusted party, the vulnerability has not received a patch as of time of publication. As a workaround, a system administrator responsible for running GeoServer can use the `GEOSERVER_LOG_FILE` setting to override any configuration option provided by the Global Settings page. The `GEOSERVER_LOG_LOCATION` parameter can be set as system property, environment variables, or servlet context parameters.

GHSA-8g7v-vjrc-x4g5 — GeoServer log file path traversal vulnerability

Affected: Maven: org.geoserver:gs-main

### Impact

This vulnerability requires GeoServer Administrator with access to the admin console to misconfigured the **Global Settings** for **log file location** to an arbitrary location.

This can be used to read files via the admin console **GeoServer Logs** page. It is also possible to leverage RCE or cause denial of service by overwriting key GeoServer files.

### Patches

This issue has been addressed in GeoServer 3.0.0: * The Global Settings page can no longer be used to specify log file location * The application parameter ``GEOSERVER_LOG_LOCATION`` mechanism (outlined below) is now the only approach available to customize the log file location.

### Workarounds

A system administrator responsible for running GeoServer can define the ``GEOSERVER_LOG_FILE`` parameter, preventing the global setting provided from being used.

The ``GEOSERVER_LOG_LOCATION`` parameter can be set as system property, environment variable, or servlet context parameter.

Environmental variable: ```bash export GEOSERVER_LOG_LOCATION=/var/opt/geoserver/logs ```

System property: ```bash -DGEOSERVER_LOG_LOCATION=/var/opt/geoserver/logs ```

Web application ``WEB-INF/web.xml``: ```xml <context-param> <param-name> GEOSERVER_LOG_LOCATION </param-name> <param-value>/var/opt/geoserver/logs</param-value> </context-param> ```

Tomcat **conf/Catalina/localhost/geoserver.xml**: ```xml <Context> <Parameter name="GEOSERVER_LOG_LOCATION" value="/var/opt/geoserver/logs" override…
