CVE-2013-6447 JBoss Seam: XML eXternal Entity (XXE) flaw in remoting
Last modified: 2015-07-31 07:56:12 EDT
It was found that the ExecutionHandler, PollHandler and SubscriptionHandler classes in JBoss Seam Remoting would unmarshall user-supplied XML, and resolve external entities in this XML. A remote attacker could use this flaw to read files accessible to the user running the application server, and potentially perform other more advanced XXE attacks.
Red Hat would like to thank Jon Passki of Coverity SRL for reporting this issue.
