resteasy XXE vulnerability
by Wang Veronica
Hi experts,
We use resteasy 3.0.6final, and XXE vulnerability was reported during penetration test.
Seems that 3.0.6final contains partial fix for XXE vulnerability, but need to set resteasy.document.expand.entity.references parameter to false explicitly. A more complete fix seems to have been done after 3.0.10.
We can upgrade to a more recent version, e.g. 3.1.2. Another option I am thinking is not to support XML Media type (we actually need to support json only). Is this a feasible approach to ultimately avoid XXE attack and any pointers to achieve this? (In our REST API code, we currently declare consume and produce annotations to support application/xml and application/json).
Is there a simple resteasy configuration to disable support of application/xml?
Thanks, Veronica

Integrating WADL into webapp running in Wildfly 11
by Simon Poet
Hi,
I have started putting together some JAX-RS endpoints for my app. I
would like to have a WADL for the whole app.
So following the User Guide I have added the following dependencies to my
pom
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-jaxrs</artifactId>
<version>3.0.24.Final</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-wadl</artifactId>
<version>3.0.24.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-wadl-undertow-connector</artifactId>
<version>3.0.24.Final</version>
</dependency>
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-undertow</artifactId>
<version>3.0.24.Final</version>
</dependency>
I have put in place a simple class to enable the JAX-RS endpoints
@ApplicationPath("/")
public class RestApp extends Application {
}
The JAX-RS end points are working as expected. When I try the wadl endpoint
/application.xml. I get the following :
<application xmlns="http://wadl.dev.java.net/2009/02"/>
So it looks like I am missing the endpoints from the WADL
I have overridden the json serialization/deserialization so that it uses
Gson
I see a code example in the user guide
UndertowJaxrsServer server = new UndertowJaxrsServer().start();
WadlUndertowConnector connector = new WadlUndertowConnector();
connector.deployToServer(server, MyApp.class);
Do I need to add this code somewhere?
Thanks in advance
Cheers, Simon
