Within JDK 10 and below, serialization is included in all systems as a part of java. Serializable methods. GeeksForGeeks maintains a description of how serialization works at its base.
For more code examples of how Serialization is used, Baeldung has an Introduction to Java Serialization. The basic premise of serialization attacks is looking for classes that execute or perform a privileged action on data that gets deserialized, then passing them the representation of that class with a malicious payload.
To understand the complete walkthrough, the presentation " Exploiting Deserialization Vulnerabilities in Java " by Matthias Kaiser in provides a sample starting on slide Much of the security research surrounding serialization is based on work by Chris Frohoff, Gabriel Lawrence, and Alvaro Munoz.
The change to remove serialization stems from the java. The most common uses are:. Developers using these methods should consider switching to alternative methods of storing and reading back their data. Eishay Smith has posted performance metrics of several different serialization libraries. When evaluating performance, an awareness of security needs to be incorporated into the baseline metric.
In cases where the default Java serialization is "faster", the exploits operate at the same speed. Isolation of the serialization APIs is discussed in project Amber. The idea is that is serialization moves from java. The discussion of this proposal did not bear fruit in the time for the JDK 11 feature set but may be worked on for a future Java version. Many organizations will benefit from a system which can monitor for risks, automating repeatable security expertise.
Java applications can embed security monitoring through tools that take advantage of the JVMTI, using instrumentation to place sensors inside an application. The benefit of using runtime instrumentation for Java security is that it does not require code changes and can integrate directly into the JRE.
It operates similarly to Aspect Oriented Programming, weaving nonintrusive bytecode into the application at sources where remote data enters the application , sinks where data can be used in an unsafe way , and passthroughs where security tracking needs to move from one Object to another. By integrating at each "sink", such as serialization's ObjectInputStream , runtime protection can add its functionality.
This functionality was critical for serialization back before deserialization filters were backported from JDK 9 and remains crucial for other attack types such as SQL Injection. Integrating this runtime protection simply involves changing the startup flag to add a javaagent.
Once startup, Tomcat will then initiate and weave detection and prevention into the application as it loads. The separation of concerns leaves applications free to focus on their business logic while the security analyzer handles the right security at the right place. The most standard java serialization that we all start from looks like this:. The easiest way to speed up the standard serialization is to use the RandomAccessFile object:.
The more sophisticated technique is to use the Kryo framework. The difference between the old and the new version is vast. TestObject write method is shown below:. Direct memory buffer class shortened, just to show the idea :.
