Description Jason Shepherd 2017-04-07 02:01:06 UTC 
It was found that the JAXP implementation used in EAP 7.0 has insecure defaults for XSL processing. An attacker could use this flaw to cause remote code execution if they are able to provide XSLT for parsing.

Comment 5 Jason Shepherd 2017-04-11 22:48:15 UTC 
Mitigation:

Doing a transform in JAXP requires the use of a 'javax.xml.transform.TransformerFactory'. If the FEATURE_SECURE_PROCESSING feature is set to 'true', it mitigates this vulnerability. Eg:

TransformerFactory factory = TransformerFactory.newInstance();
factory.setFeature(javax.xml.XMLConstants.FEATURE_SECURE_PROCESSING, true);
