Description

A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All versions < V1.17.0), Mendix SAML (Mendix 8 compatible) (All versions < V2.3.0), Mendix SAML (Mendix 9 compatible, New Track) (All versions < V3.3.1), Mendix SAML (Mendix 9 compatible, Upgrade Track) (All versions < V3.3.0). Affected versions of the module insufficiently protect from packet capture replay. This could allow unauthorized remote attackers to bypass authentication and get access to the application. For compatibility reasons, fix versions still contain this issue, but only when the not recommended, non default configuration option `'Allow Idp Initiated Authentication'` is enabled.

Affected products

Siemens Mendix SAML Module: before 1.17.0; from 2.0.0 before 2.3.0; from 3.0.0 before 3.3.1 — fixed in 1.17.0, 2.3.0, 3.3.1

How to fix

Upgrade to a fixed version: Siemens Mendix SAML Module 1.17.0, 2.3.0, 3.3.1. Check the vendor advisory for mitigations.
