In spring-core, versions v4.0.0.RC1 through v4.1.8.RELEASE, and v4.2.0.RC1 through v4.2.2.RELEASE, allow arbitrary code execution due to the `SerializableTypeWrapper` class, which allows invocation of any method on the Java classpath through its `MethodInvokeTypeProvider` method. `SerializableTypeWrapper`, implementing the `Serializable` interface, can be included in a maliciously crafted serialized object and be used to eventually invoke `Runtime.getRuntime.exec()`, if `commons-collections` is included in the classpath.
