Detailsinfo

A vulnerability was found in Siemens Mendix SAML. It has been declared as critical. This vulnerability affects an unknown function. The manipulation with an unknown input leads to a incorrect implementation of authentication algorithm vulnerability. The CWE definition for the vulnerability is CWE-303. The requirements for the product dictate the use of an established authentication algorithm, but the implementation of the algorithm is incorrect. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All versions >= V1.16.4 < V1.17.3), Mendix SAML (Mendix 8 compatible) (All versions >= V2.2.0 < V2.3.0), Mendix SAML (Mendix 9 latest compatible, New Track) (All versions >= V3.1.9 < V3.3.1), Mendix SAML (Mendix 9 latest compatible, Upgrade Track) (All versions >= V3.1.8 < V3.3.0), Mendix SAML (Mendix 9.6 compatible, New Track) (All versions >= V3.1.9 < V3.2.7), Mendix SAML (Mendix 9.6 compatible, Upgrade Track) (All versions >= V3.1.8 < V3.2.6). The affected versions of the module insufficiently verify the SAML assertions. This could allow unauthenticated remote attackers to bypass authentication and get access to the application. For compatibility reasons, fix versions still contain this issue, but only when the recommended, default configuration option `'Use Encryption'` is disabled.

The weakness was shared 03/14/2023 as ssa-851884. The advisory is shared for download at cert-portal.siemens.com. This vulnerability was named CVE-2023-25957 since 02/17/2023. There are neither technical details nor an exploit publicly available.
