Trusted execution path for protecting java applications against deserialization of untrusted data

Deserialization of untrusted data is an issue in many programming languages. In particular, deserialization of untrusted data in Java can lead to Remote Code Execution attacks. Conditions for this type of attack exist, but vulnerabilities are hard to detect. In this paper, we propose a novel sandboxing approach for protecting Java applications based on trusted execution path used for defining the deserialization behavior. We test our defensive mechanism on two main Java Framework JBoss and Jenkins and we show the effectiveness and efficiency of our system. We also discuss the limitations of our current system on newer attacks strategies.
