Summary
OpenAM vulnerable to user impersonation using SAMLv1.x SSO process
Details

Impact

OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses received as part of the SAMLv1.x Single Sign-On process. Attackers can use this fact to impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet servlet.

Patches

This problem has been patched in OpenAM 14.7.3-SNAPSHOT and later

Workarounds

One should comment servlet SAMLPOSTProfileServlet in web.xml or disable SAML in OpenAM

<servlet>
    <description>SAMLPOSTProfileServlet</description>
    <servlet-name>SAMLPOSTProfileServlet</servlet-name>
    <servlet-class>com.sun.identity.saml.servlet.SAMLPOSTProfileServlet</servlet-class>
</servlet>
...
<servlet-mapping>
    <servlet-name>SAMLSOAPReceiver</servlet-name>
    <url-pattern>/SAMLSOAPReceiver</url-pattern>
</servlet-mapping>
