Note that the schema files are loaded from the classpath. If an attacker can
manipulate the classpath, then they would be able to execute arbitrary code
anyway. I don't see how an attacker would achieve any kind of privilege
escalation.

> Key: AXIS2-6060
> URL: https://issues.apache.org/jira/browse/AXIS2-6060
> Project: Axis2
> Issue Type: Bug
> Components: codegen, wsdl
> Affects Versions: 1.8.0
> Reporter: Yiheng Cao
> Priority: Major
>
> The vulnerability is present in the class
> org.apache.axis2.wsdl.codegen.extension.JAXBRIExtension of method
> getNamespaceAwareDocumentBuilder() , which is responsible for getting a
> DocumentBuilder object that supports namespace resolution. The vulnerable
> call chain we discover is: *engage(CodeGenConfiguration
> configuration)→loadAdditionalSchemas()→getNamespaceAwareDocumentBuilder().*
> Given that the XML schema files stored in the
> /org/apache/axis2/wsdl/codegen/schema/ which is compromised by a hacker, the
> victim conducts regular process which incorporates the execution of method
> engage(), resulting in an XML External Entity (XXE) Injection attack.
