Aidan Skinner updated QPID-474:
-------------------------------
Fix Version/s: M3
> AmqPlain & Plain SaslServer don't check passwords
> -------------------------------------------------
>
> Key: QPID-474
> URL: https://issues.apache.org/jira/browse/QPID-474
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: M1, M2, M2.1
> Reporter: Martin Ritchie
> Priority: Critical
> Fix For: M3
>
>
> This is a snippet from the evaluateResponse method in AmqPlainSaslServer:
> String pwd = new String(response, authcidNullPosition + 1,
> passwordLen, "utf8");
> passwordCb.setPassword(pwd.toCharArray());
> AuthorizeCallback authzCb = new AuthorizeCallback(authzid,
> authzid);
> Callback[] callbacks = new Callback[]{nameCb, passwordCb,
> authzCb};
> _cbh.handle(callbacks);
> _complete = true;
> The authzCb is always set to true!!
> See the handler UsernamePasswordInitialiser
> else if (callback instanceof AuthorizeCallback) {
> ((AuthorizeCallback) callback).setAuthorized(true);
> As a result this will always allow access.
> (from AmqPlainSaslServer.evaluteResponse() .. follows on from above snippet)
> if (authzCb.isAuthorized())
> {
> _authorizationId = authzCb.getAuthenticationID();
> return null;
> }
> else
> {
> throw new SaslException("Authentication failed");
> }
> What needs to be done:
> This line is wrong: (from AmqPlainSaslServer)
> passwordCb.setPassword(pwd.toCharArray());
> This is done in the PrincipalDatabases
> So after the handle call
> passwordCb.getPassword() should be compared to pwd verifying the password is
> correct.
