External entities expanded by DocumentProvider
CVE: CVE-2014-7839
Component: RESTeasy
CWE: CWE-611
Severity: Moderate
Release date: 2014-11-18T00:00:00+00:00

It was found that the RESTEasy DocumentProvider did not set the external-parameter-entities and external-general-entities features appropriately, thus allowing external entity expansion. 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 XML eXternal Entity (XXE) attacks.
