Summary
OpenAM before 16.1.4 contains an open redirect vulnerability that allows attackers to redirect users to external sites because RelayState is unchecked when no relayStateUrlList is configured. Attackers can craft single sign-on links with a malicious RelayState to send users from the trusted OpenAM origin to phishing sites and bypass URL filters.
