CVE-2026-24513 (CNNVD-202602-197)
中文标题:
Kubernetes ingress-nginx 安全漏洞
英文标题:
ingress-nginx auth-url protection bypass
漏洞描述
中文描述:
Kubernetes ingress-nginx是云原生计算基金会（Cloud Native Computing Foundation）开源的Kubernetes 的入口控制器，使用NGINX作为反向代理和负载均衡器。 Kubernetes ingress-nginx存在安全漏洞，该漏洞源于auth-url Ingress注释的保护在特定配置错误情况下可能无效，可能导致身份验证失败时仍可访问Ingress。
英文描述:
A security issue was discovered in ingress-nginx where the protection afforded by the `auth-url` Ingress annotation may not be effective in the presence of a specific misconfiguration. If the ingress-nginx controller is configured with a default custom-errors configuration that includes HTTP errors 401 or 403, and if the configured default custom-errors backend is defective and fails to respect the X-Code HTTP header, then an Ingress with the `auth-url` annotation may be accessed even when authentication fails. Note that the built-in custom-errors backend works correctly. To trigger this issue requires an administrator to specifically configure ingress-nginx with a broken external component.
