Originally released in May 1995, Java is the most popular programming language in the world with over 95% of all enterprise desktops running on Java. Jave is designed to let developers “write once, run anywhere” (WORA), meaning that code written in Java is able to run on all platforms with Java support with no need for further recompilation.
Java is a concurrent, class-based, object-oriented general-purpose programming language that is celebrated for being fast, secure and reliable and can be found everywhere from the most popular websites to mobile devices and from gaming consoles to enterprise data centers and beyond. Licensed under the GNU General Public License, Java is free to download.
Java is influenced by numerous programming languages including C++, C#, Eiffel, Mesa, Modula-3, Objective-C and others and played an important role in the development many popular programming languages such as Groovy, Hack, Haxe, Kotlin, PHP, Python, Scala and others. Worldwide, there are over 9 million Java developers which, if they all banded together and formed a country, would be the 95th largest country by population in the world, or, if they created a city, it would be tied for the 20th largest in the world.
In the early 1990s, extending the power of networking computing to everyday life was considered a radical vision and a group of Sun Microsystem engineers, known as the “Green Team,” led by James Gosling, sought to realize this vision by ushering in the next wave in computing through the union of consumer devices and computers with the creation of Java. This team of Sun engineers was slightly ahead of their time as their initial focus of their efforts on interactive television and this project’s language was originally called Oak, after the tree outside of Gosling’s office, prior to its renaming to Java after Java coffee.
While Java was ahead of the curve when it came to interactive television, it emerged at the same time as the internet was beginning to take off and was a perfect match for this emerging technology. In 1995 it was announced that the Netscape Navigator internet browser would incorporate Java technology and since then major web browsers have incorporated the ability to run Java applets.
As with most coding languages, the development of Java was guided by a number of principals which influenced Java’s creation and continued development:
Struts is a free,action-based open-source, Model–view–controller (MVC) framework used to develop Java EE web applications. Released in May 2000, Struts was written by Craig McClanahan and donated to the Apache Foundation, the main goal behind Struts is the separation of the model (application logic that interacts with a database) from the view (HTML pages presented to the client) and the controller (instance that passes information between view and model).
A major security concern facing applications built using Struts is remote code execution. In 2010, Struts2, a popular Struts framework was downloaded over 1 million times in 2010 by over 18,000 organizations and included a unique class of weakness which allowed
Malicious parties to execute arbitrary code on any Struts2 web application.
Spring MVC is a Spring application framework written by Spring developers as a response to what they saw as design flaws in other popular frameworks such as insufficient separation between the presentation and request handling layers, and between the request handling layer and the model. Like Struts, Spring MVC is also an action-based framework. In 2011, Spring MVC, along with Struts, was considered one of the most downloaded vulnerable libraries due to CVE-2012-3451, this version had been downloaded over 18 million times between 2011-2012 by over 43,000 organizations
Hibernate ORM, known as simply Hibernate, is an object-relational mapping framework for the Java language. Designed for mapping Java classes to database tables and mapping from Java data types to SQL data types. Applications containing Hibernate can be threatened by SQL injections if if SQL, or HQL, queries are generated by concatenating strings. One way to protect against these is by using named parameters in any SQL or HQL.
OWASP ESAPI, the OWASP Enterprise Security API, is a free, open source, web application security control library which makes it simpler for developers to write lower-risk applications while the ESAPI libraries are designed to make it easier for programmers to retroactively add security into existing applications.
Formalized as a standard through the Java Community Process, Java Server Faces (JSF) is a Java specification for building component-based user interfaces for web applications. According to OWASP “JSF does not implement its own security model but instead relies on standard JEE security. This means that both application server security model, JAAS or other ACL implementations can be used with the JSF framework without any integration effort.” A security concern for applications which implement JSF is Access Control and Authorization issues.
JavaServer Pages (JSP) is built on top of Servlet API and allows for the embedding of Java code which is compiled and then executed when a request is received. A common threat to JSP code is cross-site scripting (XSS).
While the Java platform includes numerous features designed to improve the security of Java applications, it’s critical for developers to ensure that their Java code is vulnerability free at the earliest stages of the software development life cycle. Avoiding Java security mistakes such as not restricting access to classes and variables, not finalizing classes, relying on package scoop and others is the best place to start when securing Java code, it’s also important for developers to familiarize themselves with the common security threats facing Java code, as well as Java frameworks.

With over 95% of all enterprise desktops in the world running Java, there are serious consequences when vulnerabilities in Java code make it to production and are exploited by malicious parties. The following is a list of some of the high risk threats facing applications written in Java:
Checkmarx’s CxSAST, a static code analysis solution, stands out amongst Java testing solutions as not only the solution which will keep your Java code free from security and compliance issues, but also as the tool which will contribute to your organization’s advancement when it comes to application security maturity.
CxSAST works with the tools your developers are already using as it seamlessly integrates with most of the common development programs available at every stage of the SDLC. CxSAST’s features such as incremental code scanning and the best fix location made it ideal for any continuous integration continuous development (CICD) environment.
When vulnerabilities are detected in the Java code, CxSAST will not only identify the best fix location, but will also offer resources to the developer to understand how the attack vector work as well as remediation advice which will help them ensure similar mistakes are avoided in the future.
