All these components will help you create the web site you always imagined. The arbitrary Java deserialization was patched in RichFaces 3. Fortunately, various VariableMapper implementations were added to the whitelist starting with 4.
When a resource of that type gets requested, its send ResourceContext method gets called. RichFaces has three major version branches: May 30, Poor RichFaces. Related articles available on mastertheboss.
VariableMapperImpl was added in 4. Arbitrary Java Deserialization in RichFaces 3. Moreover, the EL implementation does not allow arbitrary fichfaces with parameterized invocations in method expressions as this has only just been added in EL 2. This includes the contentProducer field, which is expected to be a MethodExpression object. When a RichFaces 3. The latest richfacew of the respective branches are 3.
Both vulnerabilities rely on the feature to generate images, video, sounds, and other resources on the fly based on data provided in the request. The interesting thing about these classes is that they have a equals Object method, which eventually calls getType ELContext on a EL value expression. Because if one would want to create the state object, it would require the use of compatible libraries, otherwise the deserialization may fail.
That method then decodes and decompresses the data in a similar way and finally deserializes it without any further validation.
This book goes beyond the documentation to teach rcihfaces how to do that. Posted by Markus Wulftange at 3: Tested on JBoss 5. Now the problem with that is that the EL expression can be changed, even just with basic Linux utilities.
Jgoss the Application Taking a note of every contact A richer editor Let’s group our contacts Listing, adding, and removing groups Other features of the rich: X You are adviced to read this tutorial at first if you don’t have any notion about RichFaces, otherwise just go on reading. This can speed up your Project creation by adding the required configuration files to your project. There is no protection in place that would prevent one from tampering with it.
And wrapping it in a StateHolderSaver does not work because the state object is of type Object and therefore the cast to Serializable in StateHolderSaver. And after some research, two ways were found to gain remote code execution in a similar manner also affecting the latest RichFaces versions 3. Start Free Trial No credit card required.
While there are only two major JSF implementations i.

View table of contents. Newer Post Older Post Home. SerializableResourcewhich actually was introduced in 3. Richraces will be no patches after the end of support.
A Richfaces Web application needs of course a Web project.
richfacse This passes the whitelisting as ImageData extends org. The Present The kind of the past vulnerabilities led to the assumption that there may be a way to bypass the mitigations.
The resource data transmitted in the request must be an org. Especially if there is no existing sample of a valid do state object that can be tampered with. The kind of the past vulnerabilities led to the assumption that there may be a way to bypass the mitigations.
Arbitrary Java Deserialization This vulnerability is a straight forward Java deserialization vulnerability.

E-R diagram Importing the database Creating the project The class diagram Some modification to the entities Editing the template page The menu page The login page The home page Summary 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.
While the injection of arbitrary EL expressions was possible right from the beginning, there is always a need to get them triggered somehow. As you progress through the book, you will see a sample application that shows you how to build an advanced contact manager.
ResourceBuilderImpl allows remote code execution. It will show you how to get the most out of JBoss RichFaces by explaining the key components and how you can use them to enhance your applications.

Depending on the EL implementation, this allows arbitrary code execution, as demonstrated by the reporter:. The RichFaces issue RF corresponding to this vulnerability is public and actually quite detailed.
The provided data is either interpreted as a plain array of bytes or as a Java serialized object stream. First, the book introduces you to JBoss RichFaces and its components.
