Dallas Vaughan commented on CXF-6409:
-------------------------------------

Here is the sanitized request (I added formatting to the XML part for 
readability). There is no stack trace as the original XMLSecurityException gets 
swallowed and rethrown as a generic WSSecurityException (which then gets sent 
back as a fault). I found the cause by stepping through Santuario code during 
the processing of the request.

The exception thrown for the DOM-based implementation (which is also swallowed 
so there's no stack trace) is a {{java.lang.ArrayIndexOutOfBoundsException}} in 
the {{org.apache.xml.security.encryption.XMLCipher.decryptToByteArray()}} 
method at a {{System.arraycopy(encryptedBytes, 0, ivBytes, ivLen)}} call where 
{{encryptedBytes.length == 0}}, {{ivBytes.length == 16}}, and {{ivLen == 16}}. 
When I stepped through this I found that it happens during processing of an 
EncryptedData/CipherData/CipherValue element that contains an {{xop:Include}} 
element.  Since it probably expects base64 here, it failed to initialize 
{{encryptedBytes}} and {{System.arraycopy}} expects a byte array of length 16.

>             Project: CXF
>          Issue Type: Bug
>          Components: WS-* Components
>    Affects Versions: 3.0.4
>            Reporter: Dallas Vaughan
>            Assignee: Colm O hEigeartaigh
>
> When a CXF (WS-Security streaming-enabled) web service endpoint is configured 
> to use WS-Security and MTOM, CXF cannot handle requests from .NET and Metro 
> clients because it cannot process {{xop:Include}} elements that are children 
> of {{enc:CipherValue}} elements, as both of these clients will optimize any 
> large encrypted (base64-encoded binary) content by serializing it as a MIME 
> part.
> For example, when a Metro MTOM-optimized WS-Security-based request is sent to 
> a CXF endpoint, the following exception is thrown within 
> {{org.apache.xml.security.stax.impl.processor.input.AbstractDecryptInputProcessor$DecryptionThread.run()}}:
> {code}org.apache.xml.security.exceptions.XMLSecurityException: Unexpected 
> StAX-Event: START_ELEMENT{code}
> This makes it impossible for .NET and Metro clients to communicate with CXF 
> endpoints which have the MTOM and encryption policies specified.
