Authenticated privilege escalation via incomplete IdP validation
Published Jun 8, 2021 · Updated Aug 3, 2024
Privilege escalation in Siemens Mendix SAML Module before 2.1.2 allows remote authenticated users to gain elevated application access. The module configuration fails to enforce unspecified restrictions and validations imposed by the configured identity provider while processing SAML authentication data. A valid application account and network access to the SAML sign-in flow are required; Siemens has not disclosed which checks are skipped or the highest privilege obtainable.
