A patch is available in OpenAM Community Edition version 16.1.1. Users should update to this version to remediate the vulnerability. No additional mitigations are specified or required if the patch is applied.
Description
OpenAM Community Edition through version 16.0.6 contains an information exposure vulnerability in its Cross-Domain Single Sign-On (CDSSO) servlet. This flaw allows a logged-in user's raw session token to be sent via POST to an attacker-controlled URL if the user is induced to visit a crafted link. The vulnerability requires user interaction and a non-default configuration where CDSSO is enabled. It was fixed in version 16.1.1.
