Descriptions

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.

Las aplicaciones que usan tanto "spring-cloud-netflix-hystrix-dashboard" como "spring-boot-starter-thymeleaf" exponen una forma de ejecutar código enviado dentro de la ruta URI de petición durante la resolución de las plantillas de vista. Cuando es realizada una petición en "/hystrix/monitor;[user-provided data]", los elementos de la ruta que siguen a "hystrix/monitor" están siendo evaluados como expresiones SpringEL, lo que puede conllevar a una ejecución de código
