The kind of the past vulnerabilities rixhfaces to the assumption that there may be a way to bypass the mitigations. And after some research, two ways were found to gain remote code execution in a similar manner also affecting the latest RichFaces versions 3. Let’s divide the installation in a few steps: All these components will help you create the web site you always imagined.

This similarity was found in the org. Creating a New plug ‘n’ skin Installing Maven Rifhfaces the new skin Customizing the new skin Packaging and deploying the new skin Summary There is no protection in place that would prevent one from tampering with it.

The RichFaces issue RF corresponding to this vulnerability is public and actually quite detailed. And wrapping it in a StateHolderSaver does not work because the state object is of type Jbosss and therefore the cast to Serializable[] in StateHolderSaver.

That method then richaces and decompresses the data in a similar way and finally deserializes it without any further validation. In case of discovering a serious issue you will have to develop a patch yourself or switch to another framework. X You are adviced to read this tutorial at first if richfaaces don’t have any notion about RichFaces, otherwise just go on reading.


Thereby, all RichFaces versions including the latest 3. Because if one would want to create the state object, it would require the use of compatible libraries, otherwise the deserialization may fail.

When a resource of that type gets requested, its send ResourceContext method gets called. Moreover, the EL implementation does not allow arbitrary expressions with parameterized invocations in method expressions as this has only just been added in EL 2. VariableMapperImpl was added in 4. Arbitrary Java Deserialization This vulnerability is a straight forward Java deserialization vulnerability.
