CVE-2024-23656

Summary

CVE-2024-23656 affects Dex, an identity service that utilizes OpenID Connect for authentication. Despite Dex's `cmd/dex/serve.go` indicating TLS 1.2 as the minimum version, the service still supports insecure TLS 1.0 and TLS 1.1 due to the introduction of a TLS certificate reloader in version 2.37.0. This oversight leads to the ignored `tlsConfig`, which also fails to respect configured cipher suites. Version 2.38.0 of Dex addresses this security vulnerability.
