Summary

SAP HANA Database, versions - 1.0, 2.0, accepts SAML tokens with MD5 digest, an attacker who manages to obtain an MD5-digest signed SAML Assertion issued for an SAP HANA instance might be able to tamper with it and alter it in a way that the digest continues to be the same and without invalidating the digital signature, this allows them to impersonate as user in HANA database and be able to read the contents in the database.
