Apache ActiveMQ contains a deserialization of untrusted data vulnerability that may allow a remote attacker with network access to a broker to run shell commands by manipulating serialized class types in the OpenWire protocol to cause the broker to instantiate any class on the classpath.

A flaw was found in xstream. An unsafe deserialization of user-supplied XML, in conjunction with relying on the default deny list, allows a remote attacker to perform a variety of attacks including a remote code execution of arbitrary code in the context of the JVM running the XStream application. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Remedy

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 1.4.13 ```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); ```

A regression has been introduced in the commit preventing JMX re-bind. By passing an empty environment map to RMIConnectorServer, instead of the map that contains the authentication credentials, it leaves ActiveMQ open to the following attack - A remote client could create a javax.management.loading.MLet MBean and use it to create new MBeans from arbitrary URLs, at least if there is no security manager. In other words, a rogue remote client could make your Java application execute arbitrary code. Mitigation - Upgrade to Apache ActiveMQ 5.15.13

Apache ActiveMQ could allow a remote attacker to obtain sensitive information, caused by an XML External Entity Injection (XXE) error when processing XML data. By sending specially-crafted XML data to specify an XPath based selector, an attacker could exploit this vulnerability to obtain sensitive information.

It was found that XStream could deserialize arbitrary user-supplied XML content, representing objects of any type. A remote attacker able to pass XML to XStream could use this flaw to perform a variety of attacks, including remote code execution in the context of the server running the XStream application.
