Vulnerability Title
Contour has Improper JWT Verification for Non-SNI Requests on Virtual Hosts with Fallback Certificate Enabled
Vulnerability Description
Contour is a Kubernetes ingress controller using Envoy proxy. In versions 1.23.0 through 1.33.4, when an `HTTPProxy` is configured with incompatible combination of both `.spec.virtualhost.tls.enableFallbackCertificate: true` and `.spec.virtualhost.jwtProviders`, Contour does not reject the configuration. Consequently, requests from clients that do not send TLS SNI or send an unrecognized SNI (one that does not match any `HTTPProxy` FQDN) bypass configured JWT verification and are proxied to upstream services without a valid token. This issue is fixed in Contour v1.33.5. Contour now rejects and marks invalid any `HTTPProxy` resources that combine `.spec.virtualhost.tls.enableFallbackCertificate: true` with `.spec.virtualhost.jwtProviders`. Affected resources will receive a status condition with the error reason `TLSIncompatibleFeatures`. As a workaround, do not enable `.spec.virtualhost.tls.enableFallbackCertificate` on `HTTPProxy` resources that also define `.spec.virtualhost.jwtProviders`. Remove one of the two settings to avoid the invalid configuration.

projectcontour contour 加密问题漏洞
Vulnerability Description
projectcontour Contour是projectcontour团队开源的一款使用Envoy代理的Kubernetes入口控制器。 projectcontour contour 1.23.0版本至1.33.4版本存在加密问题漏洞,该漏洞源于对HTTPProxy配置中enableFallbackCertificate与jwtProviders不兼容组合的验证不当,可能导致未发送TLS SNI或发送无法识别SNI的客户端请求绕过JWT验证并代理到上游服务。
