SAP HANA Database, version - 2.0, does not correctly validate the username when performing SAML bearer token-based user authentication. It is possible to manipulate a valid existing SAML bearer token to authenticate as a user whose name is identical to the truncated username for whom the SAML bearer token was issued.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
