Red Hat Redhat Single Sign-on 7.5.0

A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity.

Due to improper authorization, Red Hat Single Sign-On is vulnerable to users performing actions that they should not be allowed to perform. It was possible to add users to the master realm even though no respective permission was granted.
