Title
OpenAM allows use of arbitrary OIDC requested claims values in id_token and user_info
Summary
Open Access Management (OpenAM) is an access management solution. In versions prior to 16.0.0, if the "claims_parameter_supported" parameter is activated, it is possible, thanks to the "oidc-claims-extension.groovy" script, to inject the value of one's choice into a claim contained in the id_token or in the user_info. In the request of an authorize function, a claims parameter containing a JSON file can be injected. This JSON file allows attackers to customize the claims returned by the "id_token" and "user_info" files. This allows for a very wide range of vulnerabilities depending on how clients use claims. For example, if some clients rely on an email field to identify a user, an attacker can choose the email address they want, and therefore assume any identity they choose. Version 16.0.0 fixes the issue.
