Overview

org.springframework.cloud:spring-cloud-netflix-hystrix-dashboard is a fault tolerance library.

Affected versions of this package are vulnerable to Arbitrary Code Execution in the request URI path during the resolution of view templates, when using both spring-cloud-netflix-hystrix-dashboard and spring-boot-starter-thymeleaf. 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.
