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.
The 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.
GeoTools includes the Jiffle language as part of the gt-process-raster-<version>
module, applications using it should check whether itβs 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.
In case you cannot upgrade at once, then the following mitigation is strongly recommended:
WEB-INF/lib
and remove the janino-<version>.jar
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.
