Description
Summary
If the "claims_parameter_supported" parameter is activated, it is possible through the "oidc-claims-extension.groovy" script, to inject the value of choice into a claim contained in the id_token or in the user_info.
Authorization function requests do not prevent a claims parameter containing a JSON file to be injected. This JSON file allows users to customize 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, users can choose to entera any email address, and therefore assume any chosen identity.
NVD description
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.
