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"/-->
