Web service provider using UsernameToken profile should throw an exception if SOAP client's
password type <> web service provider's.

                 Key: CXF-2150
                 URL: https://issues.apache.org/jira/browse/CXF-2150
             Project: CXF
          Issue Type: Bug
          Components: WS-* Components
    Affects Versions: 2.1.4
         Environment: Windows XP
            Reporter: Glen Mazza
             Fix For: 2.1.5


For WS-Security w/UsernameToken profile (standard method[1], have not tested the WS-SecurityPolicy
version with CXF 2.2), the web service provider is not checking whether the password type
being supplied by the client (PW_DIGEST or PW_TEXT) matches the type that the web service
provider is defined to handle in the cxf-servlet.xml file ("PasswordDigest" or "PasswordText").
 This creates a security problem because PW_TEXT and PW_DIGEST are handled  very differently[2]
on the service side:  for the former, the ServiceCallbackHandler validates the password, for
the latter, the WSS4J/CXF runtime does, all the ServiceCallbackHandler does is supply the
correct password to validate the client's value against.

Security hole:  If the web service provider is programmed to accept DIGEST, that means its
service-side callback handler will be supplying the correct password and will not do any validation
or throw any exceptions.  If the SOAP client sends a PW_TEXT value with *any* password, the
DIGEST-designed ServiceCallbackHandler will still be called but it won't throw any exceptions--i.e.,
the SOAP call will wrongfully complete and return an answer to the client.

CXF needs to throw an exception if the SOAP client's password type <> the web service
providers.

Client side (see [1] for source code):
        outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);

Service's cxf-servlet.xml:
                  <entry key="passwordType" value="PasswordDigest"/>
                  <!--entry key="passwordType" value="PasswordText"/-->
