Symptoms

The DistAuth application does not filter the CR (%0D) and LF (%0A) characters from the "goto" parameter which can cause a possible HTTP injection attack to happen. Even if you have configured the valid goto URL domains, the DistAuth application will still able to redirect to the URL stated in the goto URL. So the goto URL can be abused to take the user to an impostor site after login.
