What this means

OpenAM before version 16.1.4 has an open redirect vulnerability via SAML 1.x trusted-partner matching, allowing remote attackers to redirect users to phishing sites. Attackers can craft links to /SAMLAwareServlet or /SAMLPOSTProfileServlet with a destination host resembling a trusted partner. This affects OpenAM versions less than 16.1.4.

Original source description

Read the full publisher description

OpenAM before 16.1.4 contains an open redirect vulnerability that allows remote attackers to redirect users after SAML 1.x single sign-on by exploiting loose trusted-partner destination matching. Attackers can craft links to /SAMLAwareServlet or /SAMLPOSTProfileServlet with a destination host resembling a trusted partner to send authenticated users to attacker-controlled phishing sites.
