CVE-2025-40758 Details
Description
A vulnerability has been identified in Mendix SAML (Mendix 10.12 compatible) (All versions < V4.0.3), Mendix SAML (Mendix 10.21 compatible) (All versions < V4.1.2), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.21). Affected versions of the module insufficiently enforce signature validation and binding checks. This could allow unauthenticated remote attackers to hijack an account in specific SSO configurations.
A vulnerability exists in the Mendix SAML module for versions compatible with Mendix 9.24 (all versions prior to 3.6.21), Mendix 10.12 (all versions prior to 4.0.3), and Mendix 10.21 (all versions prior to 4.1.2). The issue arises because these versions inadequately enforce signature validation and binding checks, potentially allowing unauthenticated remote attackers to hijack accounts in certain single sign-on (SSO) configurations.
Users are advised to update to Mendix SAML version 3.6.21 or later for Mendix 9.24 compatibility, and to version 4.0.3 or later for Mendix 10.12 and 10.21 compatibility. The latest versions can be downloaded from the Mendix Marketplace. Additionally, ensure that SSO configurations have 'UseEncryption' enabled.
