✅ Remediation

For on-premise installations, before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update; after installing the update, restart the server by starting the JBoss Application Server process. The References section of this erratum contains a download link (you must log in to download the update). Workaround: Depending on the version of XStream used there are various usage patterns that mitigate this flaw, though we would strongly recommend using the allow list approach if at all possible as there are likely more class combinations the deny list approach may not address. Allow list approach ```java XStream xstream = new XStream(); XStream.setupDefaultSecurity(xstream); xstream.allowTypesByWildcard(new String[] {"com.misc.classname"}) ``` Deny list for XStream 1.4.16 (this should also address some previous flaws found in 1.4.7 - > 1.4.15) ```java xstream.denyTypesByRegExp(new String[]{ ".*\\.Lazy(?:Search)?Enumeration.*", "(?:java|sun)\\.rmi\\..*" }); ``` Deny list for XStream 1.4.15 ```java xstream.denyTypes(new String[]{ "sun.awt.datatransfer.DataTransferer$IndexOrderComparator", "sun.swing.SwingLazyValue", "com.sun.corba.se.impl.activation.ServerTableEntry", "com.sun.tools.javac.processing.JavacProcessingEnvironment$NameProcessIterator" }); xstream.denyTypesByRegExp(new String[]{ ".*\\$ServiceNameIterator", "javafx\\.collections\\.ObservableList\\$.*", ".*\\.bcel\\..*\\.util\\.ClassLoader" }); xstream.denyTypeHierarchy(java.io.InputStream.class ); xstream.denyTypeHierarchy(java.nio.channels.Channel.class ); xstream.denyTypeHierarchy(javax.activation.DataSource.class ); xstream.denyTypeHierarchy(javax.sql.rowset.BaseRowSet.class ); ``` Deny list for XStream 1.4.13 ```java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class }); ``` Deny list for XStream 1.4.7 -> 1.4.12 ```java xstream.denyTypes(new String[]{ "javax.imageio.ImageIO$ContainsFilter" }); xstream.denyTypes(new Class[]{ java.lang.ProcessBuilder.class, java.beans.EventHandler.class, java.lang.ProcessBuilder.class, java.lang.Void.class, void.class }); ``` Deny list for versions prior to XStream 1.4.7 ```java xstream.registerConverter(new Converter() { public boolean canConvert(Class type) { return type != null && (type == java.beans.EventHandler.class || type == java.lang.ProcessBuilder.class || type == java.lang.Void.class || void.class || type.getName().equals("javax.imageio.ImageIO$ContainsFilter") || Proxy.isProxy(type)); } public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } public void marshal(Object source, HierarchicalStreamWriter writer, MarshallingContext context) { throw new ConversionException("Unsupported type due to security reasons."); } }, XStream.PRIORITY_LOW); ```
