CVE-2023-30845 (CNNVD-202304-2109)
中文标题:
Google ESPv2 授权问题漏洞
英文标题:
ESPv2 vulnerable to JWT authentication bypass via `X-HTTP-Method-Override` header
漏洞描述
中文描述:
Google ESPv2是美国谷歌(Google)公司的一种通用的L7服务代理。可为JSON/REST或gRPC API服务启用API管理功能。 Google ESPv2 2.20.0至2.42.0版本存在授权问题漏洞,该漏洞源于API 客户端可以制作恶意的标头值绕过 JWT 身份验证。
英文描述:
ESPv2 is a service proxy that provides API management capabilities using Google Service Infrastructure. ESPv2 2.20.0 through 2.42.0 contains an authentication bypass vulnerability. API clients can craft a malicious `X-HTTP-Method-Override` header value to bypass JWT authentication in specific cases. ESPv2 allows malicious requests to bypass authentication if both the conditions are true: The requested HTTP method is **not** in the API service definition (OpenAPI spec or gRPC `google.api.http` proto annotations, and the specified `X-HTTP-Method-Override` is a valid HTTP method in the API service definition. ESPv2 will forward the request to your backend without checking the JWT. Attackers can craft requests with a malicious `X-HTTP-Method-Override` value that allows them to bypass specifying JWTs. Restricting API access with API keys works as intended and is not affected by this vulnerability. Upgrade deployments to release v2.43.0 or higher to receive a patch. This release ensures that JWT authentication occurs, even when the caller specifies `x-http-method-override`. `x-http-method-override` is still supported by v2.43.0+. API clients can continue sending this header to ESPv2.
