info:
|
|
name: Spring Cloud Netflix Hystrix Dashboard <2.2.10 - Remote Code Execution
|
|
author: forgedhallpass
|
|
severity: high
|
|
description: |
|
|
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.
|
|
impact: |
|
|
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the target system.
|
|
remediation: |
|
|
Upgrade to Spring Cloud Netflix Hystrix Dashboard version 2.2.10 or later to mitigate this vulnerability.
