Fortunately, various VariableMapper implementations were added to the whitelist starting with 4. In case of discovering a serious issue you will have to develop a patch yourself or switch to another framework. Making the Application Structure Skinnability and dynamic skin change Selecting the application skin User-selected application skin Passing application parameters using components.


Let’s divide the installation in a few steps: X You are adviced to read this tutorial at first if you don’t have any notion about RichFaces, otherwise just go on reading. You will learn how to create and customize your own components and add them to richfacex new or existing applications. As we can’t expect official patches, one way to mitigate all these vulnerabilities is to block requests to the concerned URLs:.

And wrapping it in a StateHolderSaver does not work 3.33 the state object is of type Object[] and therefore the cast to Serializable[] in StateHolderSaver. Step 1 download richfaces latest stable release http: The provided data is either interpreted as a plain array of bytes or as a Java serialized object stream.

ResourceBuilderImpl allows remote code execution. JBoss Tools has a plugin specific for Rich Faces. As the patch to CVE introduced in 4.

It uses many examples of AJAX components which, among others, include: Depending on the EL implementation, this allows arbitrary code execution, as demonstrated by the reporter:. Once created you need to add a set of libraries to your Web Project. Here’s the list of libraries which need to be included in your project: There will be no patches after the end of support.

This can speed up your Project creation by adding the required configuration files to your project. Tested on JBoss 5. And as the value expression has to be evaluated to determine its resulting type, this can be used as a Java deserialization primitive to execute EL value expressions on deserialization.

This vulnerability is a straight forward Java deserialization vulnerability. Step 3 Add libraries to your Web Project A Richfaces project needs a set of core libraries plus a few dependancies which needs to be downloaded. It has been shown that all RichFaces versions 3.
