Why It Matters

A vulnerability has been identified in Mendix SAML (Mendix 7 compatible) (All versions >= V1.17.3 < V1.18.0), Mendix SAML (Mendix 7 compatible) (All versions >= V1.16.4 < V1.17.3), Mendix SAML (Mendix 8 compatible) (All versions >= V2.3.0 < V2.4.0), Mendix SAML (Mendix 8 compatible) (All versions >= V2.2.0 < V2.3.0), Mendix SAML (Mendix 9 latest compatible, New Track) (All versions >= V3.3.1 < V3.6.1), 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 >= V3.3.0 < V3.6.0), Mendix SAML (Mendix 9 latest compatible, Upgrade Track) (All versions >= V3.1.8 < V3.3.0), Mendix SAML (Mendix 9.12/9.18 compatible, New Track) (All versions >= V3.3.1 < V3.3.15), Mendix SAML (Mendix 9.12/9.18 compatible, Upgrade Track) (All versions >= V3.3.0 < V3.3.14), 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. This CVE entry describes the incomplete fix for CVE-2023-25957 in a specific non default configuration.

Suggested hunting (rule-based inference)

SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.

Matched authentication-weakness (CWE-287); network-unauthenticated (CVSS AV:N, CVSS PR:N, CVSS UI:N)

Exposure

  1. Identify affected authentication surfaces and compare versions with the advisory.Telemetry: Application inventory · A CWE match is not proof of local exposure. · Rule authentication-weakness
  2. Identify devices reporting this CVE and note which expose the affected service to untrusted networks.Telemetry: DeviceTvmSoftwareVulnerabilities · A network-reachable, no-privilege vector makes internet-facing instances the first exposure question. · Rule network-unauthenticated

Exploitation evidence

  1. Review unexpected successful sign-ins and changes to privileged accounts on affected systems.Telemetry: SigninLogs · Access anomalies are relevant to authentication weaknesses. · Rule authentication-weakness
Show more (2)

Exploitation evidence

  1. Review inbound connections to the affected service from unexpected sources since the advisory date.Telemetry: DeviceNetworkEvents · Hunting hypothesis from the CVSS vector; it does not show that exploitation occurred. · Rule network-unauthenticated

Response

  1. Verify the vendor fix and review privileged access after remediation.Telemetry: Identity audit logs · Post-change review checks the response. · Rule authentication-weakness
