In Spring Cloud Function versions 3.1.6, 3.2.2 and older unsupported versions, when using routing functionality it is possible for a user to provide a specially crafted SpEL as a routing-expression that may result in remote code execution and access to local resources.

Spring Integration framework provides Kryo Codec implementations as an alternative for Java (de)serialization. When Kryo is configured with default options, all unregistered classes are resolved on demand. This leads to the "deserialization gadgets" exploit when provided data contains malicious code for execution during deserialization. In order to protect against this type of attack, Kryo can be configured to require a set of trusted classes for (de)serialization. Spring Integration should be proactive against blocking unknown "deserialization gadgets" when configuring Kryo in code.

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); ```

Impact The vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.17.

Workarounds See workarounds for the different versions covering all CVEs.

References See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-29505.
