MEDIUM 5.4EPSS 0.69%
Does this matter?
Lower severity and a low EPSS score (0.69%). Track it; it rarely justifies an emergency change on its own.
Description
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.
