Summary: ValidateXMLFile.java:55 (XML External Entity Injection)
Key: AXIS2-5878
URL: https://issues.apache.org/jira/browse/AXIS2-5878
Project: Axis2
Issue Type: Bug
Components: jaxws
Affects Versions: 1.7.6
Reporter: Donald Kwakkel
Priority: Critical
XML parser configured in ValidateXMLFile.java:55 does not prevent nor limit
external entities resolution. This can expose the parser to an XML External
Entities attack.
Proposed solution: Always disable external entities when creating a
DocumentBuilderFactory:
{code:java}
public static DocumentBuilderFactory createDocumentBuilderFactory() {
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
try {
factory.setFeature("http://xml.org/sax/features/external-general-entities";,
false);
factory.setFeature("http://xml.org/sax/features/external-parameter-entities";,
false);
}
catch (ParserConfigurationException e) {
throw new IllegalStateException(e);
}
return factory;
}
{code}
