    Summary: OpenAM Session Hijacking via CDSSO

    Details: Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the `Cross-Domain Single Sign-On` (`CDSSO`) servlet allows a logged-in user's raw OpenAM session token to be POSTed to an attacker-controlled URL. An attacker who induces an authenticated victim to visit a crafted URL can receive the session credential and potentially hijack the session. Deployments must have `CDSSO` enabled, as is common in multi-domain deployments, and exploitation is additionally gated on a non-default configuration being absent. This issue is fixed in version 16.1.1.
