CVE-2024-23656

Dex is an identity service that uses OpenID Connect to drive authentication for other apps. Dex 2.37.0 serves HTTPS with insecure TLS 1.0 and TLS 1.1. `cmd/dex/serve.go` line 425 seemingly sets TLS 1.2 as minimum version, but the whole `tlsConfig` is ignored after `TLS cert reloader` was introduced in v2.37.0. Configured cipher suites are not respected either. This issue is fixed in Dex 2.38.0.

Summary
  • (es) Dex es un servicio de identidad que utiliza OpenID Connect para impulsar la autenticación de otras aplicaciones. Dex 2.37.0 sirve HTTPS con TLS 1.0 y TLS 1.1 inseguros. La línea 425 de `cmd/dex/serve.go` aparentemente establece TLS 1.2 como versión mínima, pero el `tlsConfig` completo se ignora después de que se introdujo el `TLS cert reloader` en v2.37.0. Tampoco se respetan los conjuntos de cifrado configurados. Este problema se solucionó en Dex 2.38.0.
