name: RCE through SpringEL expressions in Spring Cloud Netflix Hystrix Dashboard < 2.2.10.RELEASE
|

author: forgedhallpass

severity: high

description: |
|
|
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.
