CVE-2014-3490: High severity jboss enterprise application platform vulnerability
IssueDescription:
It was found that the fix for CVE-2012-0818 was incomplete: external parameter entities were not disabled when the resteasy.document.expand.entity.references parameter was set to false. A remote attacker able to send XML requests to a RESTEasy endpoint could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.
Other sources
RESTEasy 2.3.1 before 2.3.8.SP2 and 3.x before 3.0.9, as used in Red Hat JBoss Enterprise Application Platform (EAP) 6.3.0, does not disable external entities when the resteasy.document.expand.entity.references parameter is set to false, which allows remote attackers to read arbitrary files and have other unspecified impact via unspecified vectors, related to an XML External Entity (XXE) issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0818.
