Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for OpenIdentityPlatform/OpenAM, org.openidentityplatform.openam:openam-federation-library, org.openidentityplatform.openam:openam-federation-library.
  2. 2Review the reported fix. Update OpenIdentityPlatform/OpenAM to 16.1.1; org.openidentityplatform.openam:openam-federation-library to 16.1.1; org.openidentityplatform.openam:openam-federation-library to 16.1.1 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, certain federation endpoints in a non-default clustered configuration inconsistently encode user-supplied parameters rendered into HTML in the SAML2 cluster cookie-hash redirect path. An unauthenticated attacker can induce a user to follow a crafted request and execute script in the OpenAM origin. This issue is fixed in version 16.1.1.
