CVE-2021-22053: Spring Cloud Netflix Hystrix DashBoard <2.2.10 – Remote Code Execution

漏洞描述

Spring Cloud Netflix Hystrix Dashboard prior to version 2.2.10 is susceptible to remote code execution. Applications using both `spring-cloud-netflix-hystrix-dashboard` and `spring-boot-starter-thymeleaf` expose a way to execute code submitted within the request URI path during the resolution of view templates. When a request is made at `/hystrix/monitor;[user-provided data]`, the path elements following `hystrix/monitor` are being evaluated as SpringEL expressions, which can lead to code execution.
