GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. An arbitrary file upload vulnerability exists in versions prior to 2.23.4 and 2.24.1 that enables an authenticated administrator with permissions to modify coverage stores through the REST Coverage Store API to upload arbitrary file contents to arbitrary file locations which can lead to remote code execution. Coverage stores that are configured using relative paths use a GeoServer Resource implementation that has validation to prevent path traversal but coverage stores that are configured using absolute paths use a different Resource implementation that does not prevent path traversal. This vulnerability can lead to executing arbitrary code. An administrator with limited privileges could also potentially exploit this to overwrite GeoServer security files and obtain full administrator privileges. Versions 2.23.4 and 2.24.1 contain a fix for this issue.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.23.4 and 2.24.1 that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another user's browser when viewed in the GWC Demos Page. Access to the GWC Demos Page is available to all users although data security may limit users' ability to trigger the XSS. Versions 2.23.4 and 2.24.1 contain a patch for this issue.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.23.4 and 2.24.1 that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another user's browser when viewed in the MapML HTML Page. The MapML extension must be installed and access to the MapML HTML Page is available to all users although data security may limit users' ability to trigger the XSS. Versions 2.23.4 and 2.24.1 contain a patch for this issue.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.23.3 and 2.24.1 that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another user's browser when viewed in the WMS GetMap OpenLayers Output Format. Access to the WMS OpenLayers Format is available to all users by default although data and service security may limit users' ability to trigger the XSS. Versions 2.23.3 and 2.24.1 contain a patch for this issue.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.23.2 and 2.24.1 that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another administrator’s browser when viewed in the GWC Seed Form. Access to the GWC Seed Form is limited to full administrators by default and granting non-administrators access to this endpoint is not recommended. Versions 2.23.2 and 2.24.1 contain a fix for this issue.

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. A stored cross-site scripting (XSS) vulnerability exists in versions prior to 2.23.4 and 2.24.1 that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another user's browser when viewed in the WMS GetMap SVG Output Format when the Simple SVG renderer is enabled. Access to the WMS SVG Format is available to all users by default although data and service security may limit users' ability to trigger the XSS. Versions 2.23.4 and 2.24.1 contain a fix for this issue.
