Geoserver 2 14 2

GeoServer 2, in some configurations, allows remote attackers to execute arbitrary code via java.lang.Runtime.getRuntime().exec in wps:LiteralData within a wps:Execute request, as exploited in the wild in June 2023.RCE in JiffleThe Jiffle map algebra language, provided by jai-ext, allows efficiently execute map algebra over large images. A vulnerability CVE-2022-24816 has been recently found in Jiffle, that allows a Code Injection to be performed by properly crafting a Jiffle invocation.In the case of GeoServer, the injection can be performed from a remote request.AssessmentGeoTools includes the Jiffle language as part of the gt-process-raster- module, applications using it should check whether it’s possible to provide a Jiffle script from remote, and if so, upgrade or remove the functionality (see also the GeoServer mitigation, below).The issue is of particular interest for GeoServer users, as GeoServer embeds Jiffle in the base WAR package. Jiffle is available as a OGC function, for usage in SLD rendering transformations.This allows for a Remote Code Execution in properly crafted OGC requests, as well as from the administration console, when editing SLD files.MitigationsIn case you cannot upgrade at once, then the following mitigation is strongly recommended:Stop GeoServerOpen the war file, get into WEB-INF/lib and remove the janino-.jarRestart GeoServer.This effectively removes the Jiffle ability to compile scripts in Java code, from any of the potential attack vectors (Janino is the library used to turn the Java code generated from the Jiffle script, into executable bytecode).GeoServer should still work properly after the removal, but any attempt to use Jiffle will result in an exception.References

A remote. Many submodules link to a specific branch, so make sure you get the right one (ask a developer if you are unsure)! % cd geoserver/externals/geoserver % git pull origin 2.7.xIn order for this update to be reflected in the server project, it must be commited like any other change: % cd ../ % git add geoserver % git commit -m "update geoserver submodule"You can then push this change to your fork and create a pull request, like any other commit.Release BranchesDuring regular development, server changes are commited to the master branch. Prior to a release, a release branch (of the form r4.7) is created. Any changes should be made against that branch instead, and backported to master if necessary.When commiting a change to the release branch, note the commit id: [r4.7 0c66de5] update geoserver submoduleTo backport this commit to master, switch to the master branch and use cherry-pick to copy the commit. Remember to push your change up to the server repository: % git checkout master % git cherry-pick 0c66de5 % git push upstream masterCertain submodules (mainly geoserver) will also have release specific branches. If you are updating a submodule on the release branch, first check if it has its own branch for this release (usually of the form server-4.7). Ask a developer if you are unsure.What's nextTo build Boundless Server, go to step 2 of the Quickstart.For more information about the build system, see the Build System Overview.For information on the individual components that comprise server, follow the links in the Modules section.If you are preparing for a new release of Boundless Server, refer to the Release Procedure section.QuickstartClone the repository: % git clone git://github.com/boundlessgeo/server.git server % cd serverInitialize submodule dependencies: % git submodule update --init --recursiveDo a full build:Or build the module of your choice:Build System
