CVE-2024-36404

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.

### 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: ``` new org.geotools.xsd.StreamingParser( new org.geotools.filter.v1_0.OGCConfiguration(), new java.io.ByteArrayInputStream("<Filter></Filter>".getBytes()), "java.lang.Thread.sleep(5000)") .parse(); ``` ### 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.

GeoTools es una librería Java de código abierto que proporciona herramientas para datos geoespaciales. Antes de las versiones 31.2, 30.4 y 29.6, la ejecución remota de código (RCE) es posible si una aplicación utiliza cierta funcionalidad de GeoTools para evaluar las expresiones XPath proporcionadas por la entrada del usuario. Las versiones 31.2, 30.4 y 29.6 contienen una solución para este problema. Como workaround, GeoTools puede operar con funcionalidad reducida eliminando el archivo jar `gt-complex` de la aplicación. Como ejemplo del impacto, el esquema de aplicación "almacén de datos" no funcionaría sin la capacidad de utilizar expresiones XPath para consultar contenido complejo. Alternativamente, se puede utilizar un jar GeoTools de reemplazo directo de SourceForge para las versiones 31.1, 30.3, 30.2, 29.2, 28.2, 27.5, 27.4, 26.7, 26.4, 25.2 y 24.0. Estos archivos jar se pueden descargar únicamente y no están disponibles en maven central, con el objetivo de proporcionar rápidamente una solución a las aplicaciones afectadas.
