Short explanation
OpenAM versions prior to 16.1.4 contain an open redirect vulnerability in the SAML 1.x single sign‑on flow due to lax trusted‑partner destination matching. Attackers can craft links to /SAMLAwareServlet or /SAMLPOSTProfileServlet with a destination host resembling a trusted partner, causing authenticated users to be sent to attacker‑controlled phishing sites. This enables credential theft and session hijacking. Patch status is unverified and no active exploitation is reported.
Redirecting authenticated users to malicious sites can lead to credential compromise and session takeover.
What should be done?
- Upgrade OpenAM to 16.1.4 or later
- Enforce strict destination validation per vendor guidance
- Monitor for suspicious redirect activity
- Follow official advisories as patch status is unknown

Show the technical text from the sources
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.
