- Summary
- s2n-tls's mTLS API ordering may skip client authentication
- Details
-
Impact
An API ordering issue in s2n-tls can cause client authentication to unexpectedly not be enabled on the server when it otherwise appears to be. Server applications are impacted if client authentication is enabled by calling s2nconnectionsetconfig() before calling s2nconnectionsetclientauthtype().
Applications are not impacted if these APIs are called in the opposite order, or if client authentication is enabled on the config with s2nconfigsetclientauth_type(). s2n-tls clients verifying server certificates are not impacted.
Impacted versions: < v1.5.0.
Patches
The patch is included in v1.5.0 [1].
Workarounds
Applications can workaround this issue by calling s2nconnectionsetconfig() after calling s2nconnectionsetclientauthtype(), or by enabling client authentication on the config with s2nconfigsetclientauth_type().
