How Java Vulnerability Making Java Customization Task Of Developers Difficult?

There are many java applications in the market that are vulnerable. The Java Serialization vulnerability is a big deal – it is not completely automated, but it is still pretty easy to explore and exploit this issue in applications. It enables the attacker to take over the whole server on which the app is hosted. This lets them to steal or corrupt any data accessible from that server, make changes in app, steal its code, or even use that server as a launching point for future attacks as they are inside the data center. This has made java customization job difficult for developers.

What is the vulnerability all about?

Serialization is used by programmers to transfer complex data structures between computers. It is a simple way to take lots of “objects” and transform them into single data stream that can be de-serialized at the other end. This is not a problem in Java or its libraries; it is rather a powerful functionality that companies should not expose to unfaithful users.

Major implications for companies

Companies need to find all the regions where they are using deserialization on untrusted data, as it is likely to be more exploitable. Searching their code is a half thing as libraries and frameworks that they are using in their applications might also create this kind of exposure.

It is tricky job to mitigate deserialization vulnerability as it can occur anywhere in your app server, framework, custom code, or libraries. Developers are finding s job difficult with this issue as eliminating commons collections from app servers running the library won’t help them completely as other libraries could experience similar issue.

Developers can resolve this issue by using something like RASP (Runtime Application Self-Protection). They can add an agent to their Java environment that hardens everywhere that utilizes the deserialization engine and protects it from exploitation.
