GeoTools Remote Code Execution (RCE) vulnerability in evaluating XPath expressions
Summary
Remote Code Execution (RCE) is possible if an application uses certain GeoTools functionality to evaluate XPath expressions supplied by user input.
Details
The following methods pass XPath expressions to the commons-jxpath library which can execute arbitrary code and would be a security issue if the XPath expressions are provided by user input.
org.geotools.appschema.util.XmlXpathUtilites.getXPathValues(NamespaceSupport, String, Document)org.geotools.appschema.util.XmlXpathUtilites.countXPathNodes(NamespaceSupport, String, Document)org.geotools.appschema.util.XmlXpathUtilites.getSingleXPathValue(NamespaceSupport, String, Document)org.geotools.data.complex.expression.FeaturePropertyAccessorFactory.FeaturePropertyAccessor.get(Object, String, Class<T>)org.geotools.data.complex.expression.FeaturePropertyAccessorFactory.FeaturePropertyAccessor.set(Object, String, Object, Class)org.geotools.data.complex.expression.MapPropertyAccessorFactory.new PropertyAccessor() {...}.get(Object, String, Class<T>)org.geotools.xsd.StreamingParser.StreamingParser(Configuration, InputStream, String)
PoC
The following inputs to StreamingParser will delay the response by five seconds:
Impact
This vulnerability can lead to executing arbitrary code.
Mitigation
GeoTools can operate with reduced functionality by removing the gt-complex jar from your application. As an example of the impact application schema datastore would not function without the ability to use XPath expressions to query complex content.
The SourceForge download page lists drop-in-replacement jars for GeoTools: 31.1, 30.3, 30.2, 29.2, 28.2, 27.5, 27.4, 26.7, 26.4, 25.2, 24.0. These jars are for download only and are not available from maven central, intended to quickly provide a fix to affected applications.

GeoTools is an open source Java library that provides tools for geospatial data. Prior to versions 31.2, 30.4, and 29.6, Remote Code Execution (RCE) is possible if an application uses certain GeoTools functionality to evaluate XPath expressions supplied by user input. Versions 31.2, 30.4, and 29.6 contain a fix for this issue. As a workaround, GeoTools can operate with reduced functionality by removing the `gt-complex` jar from one's application. As an example of the impact, application schema `datastore` would not function without the ability to use XPath expressions to query complex content. Alternatively, one may utilize a drop-in replacement GeoTools jar from SourceForge for versions 31.1, 30.3, 30.2, 29.2, 28.2, 27.5, 27.4, 26.7, 26.4, 25.2, and 24.0. These jars are for download only and are not available from maven central, intended to quickly provide a fix to affected applications.
