Name of the Vulnerable Software and Affected Versions OpenAM versions prior to 16.1.4

Description An incomplete output encoding issue exists that allows a SAML 1.x identity provider to alter attribute values by injecting unencoded content into the service provider auto-submitted form. Attackers who control a trusted identity provider can craft assertion attribute names or values that reach the target application in a modified form, which undermines the integrity of the received attributes.

Recommendations Update OpenAM to version 16.1.4 or later.
