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.
