openam-federation-library is vulnerable to User Impersonation. The vulnerability exists because the processResponse function of SAMLUtils.java does not properly validate the signature of a SAML responses received as part of the SAMLv1.x Single Sign-On process, which allows an attacker to exploit this flaw and impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet.
