OGNL Technology
Object-Graph Navigation Language (OGNL) is an open-source Expression Language (EL) for Java, which, while using simpler expressions than the full range of those supported by the Java language, allows getting and setting properties (through defined setProperty and getProperty methods, found in JavaBeans), and execution of methods of Java classes. It also allows for simpler array manipulation. It is aimed to be used in Java EE applications with taglibs as expression language. OGNL was created by Luke Blanshard and Drew Davidson of OGNL Technology. OGNL development was continued by OpenSymphony, which closed in 2011. OGNL is developed now as a part of the Apache Commons. OGNL Technology OGNL began as a way to map associations between front-end components and back-end objects using property names. As these associations gathered more features, Drew Davidson created Key-Value Coding language (KVCL). Luke Blanshard then reimplemented KVCL using ANTLR and started using the name OGN ...

Apache Struts
Apache Struts 2 is an open-source web application framework for developing Java EE web applications. It uses and extends the Java Servlet API to encourage developers to adopt a model–view–controller (MVC) architecture. The WebWork framework spun off from Apache Struts 1 aiming to offer enhancements and refinements while retaining the same general architecture of the original Struts framework. In December 2005, it was announced that WebWork 2.2 was adopted as Apache Struts 2, which reached its first full release in February 2007. Struts 2 has a history of critical security bugs, many tied to its use of OGNL technology; some vulnerabilities can lead to arbitrary code execution. In October 2017, it was reported that failure by Equifax to address a Struts 2 vulnerability advised in March 2017 was later exploited in the data breach that was disclosed by Equifax in September 2017.

Scripting Languages
A scripting language or script language is a programming language that is used to manipulate, customize, and automate the facilities of an existing system. Scripting languages are usually interpreted at runtime rather than compiled. A scripting language's primitives are usually elementary tasks or API calls, and the scripting language allows them to be combined into more programs. Environments that can be automated through scripting include application software, text editors, web pages, operating system shells, embedded systems, and computer games. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, it is also known as an extension language. Scripting languages are also sometimes referred to as very high-level programming languages, as they sometimes operate at a high level of abstraction, or as control languages, particularly for job control languages on mainframes. The term ''scripting lang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MVEL
MVFLEX Expression Language (MVEL) is a hybrid dynamic/statically typed, embeddable Expression Language and runtime for the Java Platform. Originally started as a utility language for an application framework, the project is now developed completely independently. MVEL is typically used for exposing basic logic to end-users and programmers through configuration such as XML files or annotations. It may also be used to parse simple JavaBean expressions. The runtime allows MVEL expressions to be executed either interpretively, or through a pre-compilation process with support for runtime bytecode generation to remove overhead. Since MVEL is meant to augment Java-based software, it borrows most of its syntax directly from the Java programming language with some minor differences and additional capabilities. For example: as a side effect of MVEL's typing model, which treats class and method references as regular variables, it is possible to use both class and function pointers (b ...

Ars Technica
''Ars Technica'' is a website covering news and opinions in technology, science, politics, and society, created by Ken Fisher and Jon Stokes in 1998. It publishes news, reviews, and guides on issues such as computer hardware and software, science, technology policy, and video games. ''Ars Technica'' was privately owned until May 2008, when it was sold to Condé Nast Digital, the online division of Condé Nast Publications. Condé Nast purchased the site, along with two others, for $25 million and added it to the company's ''Wired'' Digital group, which also includes ''Wired'' and, formerly, Reddit. The staff mostly works from home and has offices in Boston, Chicago, London, New York City, and San Francisco. The operations of ''Ars Technica'' are funded primarily by advertising, and it has offered a paid subscription service since 2001.

Arbitrary Code Execution
In computer security, arbitrary code execution (ACE) is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution. A program that is designed to exploit such a vulnerability is called an arbitrary code execution exploit. The ability to trigger arbitrary code execution over a network (especially via a wide-area network such as the Internet) is often referred to as remote code execution (RCE). Vulnerability types There are a number of classes of vulnerability that can lead to an attacker's ability to execute arbitrary commands or code. For example: * Memory safety vulnerabilities such as buffer overflows or over-reads. * Deserialization vulnerabilities * Type confusion vulnerabilities * GNU LDD arbitrary code execution Methods Arbitrary code execution is commonly achieved through control over th ...

FreeMarker
Apache FreeMarker is a free Java-based template engine, originally focusing on dynamic web page generation with MVC software architecture. However, it is a general purpose template engine, with no dependency on servlets or HTTP or HTML, and is thus often used for generating source code, configuration files or e-mails. History FreeMarker had a somewhat hectic history until about 2004, caused by paradigm shifts and other significant changes on multiple occasions. FreeMarker 1 (now known as FreeMarker Classic, a separate project) was originally written by Benjamin Geer and Mike Bayer. From 2002, the new project lead was Jonathan Revusky, who released FreeMarker 2, which started a sequence of several substantial changes. The main goal of the changes was to make the template language more strict, i.e., to detect as many of the typos and other typical mistakes as possible. Also, automatic object wrapping was introduced, along with gradual advancement of the type system of the templa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thymeleaf
Thymeleaf is a Java XML/XHTML/HTML5 template engine that can work both in web (servlet-based) and non-web environments. It is better suited for serving XHTML/HTML5 at the view layer of MVC-based web applications, but it can process any XML file even in offline environments. It provides full Spring Framework integration. In web applications Thymeleaf aims to be a complete substitute for JavaServer Pages (JSP), and implements the concept of ''Natural Templates'': template files that can be directly opened in browsers and that still display correctly as web pages. Thymeleaf is open-source software, licensed under the Apache License 2.0. Features From the project's website: Thymeleaf Features * Java template engine for XML, XHTML and HTML5. * Works both in web and non-web (offline) environments. No hard dependency on the Servlet API. * Based on modular feature sets called ''dialects''. ** Dialect features (e.g.: evaluation, iteration, etc.) are applied by linking them to template' ...

MyBatis
MyBatis is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations. MyBatis is free software that is distributed under the Apache License 2.0. MyBatis is a fork of iBATIS 3.0 and is maintained by a team that includes the original creators of iBATIS. Feature summary Unlike ORM frameworks, MyBatis does not map Java objects to database tables but Java methods to SQL statements. MyBatis lets you use all your database functionality like stored procedures, views, queries of any complexity and vendor proprietary features. It is often a good choice for legacy or de-normalized databases or to obtain full control of SQL execution. It simplifies coding compared to JDBC. SQL statements are executed with a single line. MyBatis provides a mapping engine that maps SQL results to object trees in a declarative way. SQL statements can be built dynamically by using a built-in language with XML-like syntax or with Apac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Click
Apache Click is a page and component oriented web application framework for the Java language and is built on top of the Java Servlet API. It is a free and open-source project distributed under the Apache license and runs on any JDK installation (1.5 or later). Click was initially created by Malcolm Edgar as the click.sourceforce.net project in 2003. The project then graduated to an Apache top-level project in November 2009 with Bob Schellink. The project was retired in May 2014. Overview The main design goals are simplicity, ease of use, performance and scalability. To achieve these goals Click leverages an intuitive page and component oriented design. Pages and components provide good encapsulation of web concepts and enables rapid application development. Click takes a pragmatic approach and expose few abstractions to learn and understand. The Java Servlet API is fully exposed to the developer which eases the upgrade path from an action based framework to a component base ...
