CVE-2011-5245: Infoleak
First published: Mon Jan 30 2012(Updated: )
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.
