Description David Jorm 2012-01-30 04:48:37 UTC

RESTEasy permits XXE (XML eXternal Entity) attacks. If a RESTEasy endpoint is deployed, a user can submit a request containing an external XML entity. This XML entity will be resolved, allowing a remote attacker to read files in the context of the user running the application server. This flaw affects DOM Document, JAXB and Fast Infoset (FI) input.

Comment 15 Murray McAllister 2012-06-19 02:45:11 UTC

The fix for CVE-2012-0818 is not enabled by default. After installing the relevant updates, if applications on your server expose RESTEasy XML endpoints, add the following snippet to their web.xml file to disable entity expansion in RESTEasy:

<context-param>
        <param-name>resteasy.document.expand.entity.references</param-name>
        <param-value>false</param-value>
</context-param>

Note that this <context-param> setting has precedence over <init-param>, and will override a contrary setting in an <init-param> element.

This was also assigned CVE-2011-5245:

The readFrom function in providers.jaxb.JAXBXmlTypeProvider in RESTEasy before 2.3.2 allows remote attackers to read arbitrary files via an external entity reference in a Java Architecture for XML Binding (JAXB) input, aka an XML external entity (XXE) injection attack, a similar vulnerability to CVE-2012-0818.
