OpenAM before 16.1.4 Open Redirect via SAML 1.x Trusted-Partner Matching
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.
