Description Preview

Spring Cloud Netflix versions 2.2.x prior to 2.2.4, versions 2.1.x prior to 2.1.6, and older unsupported versions contain a vulnerability in the Hystrix Dashboard proxy.stream endpoint. This vulnerability allows applications to make requests to any server reachable by the server hosting the dashboard, potentially exposing sensitive systems to unauthorized access.

Overview

The vulnerability in Spring Cloud Netflix's Hystrix Dashboard allows a malicious user to abuse the proxy.stream endpoint to send requests to arbitrary servers that are reachable from the dashboard host. This represents a server-side request forgery (SSRF) vulnerability (CWE-610) that could be exploited to access internal services not intended for public access. An attacker could potentially use this vulnerability to bypass network security controls, access internal services, or perform reconnaissance on internal network architecture.

Remediation

To remediate this vulnerability, users should update to the following versions:

  • For Spring Cloud Netflix 2.2.x: Update to version 2.2.4 or later
  • For Spring Cloud Netflix 2.1.x: Update to version 2.1.6 or later
  • For older versions: Upgrade to a supported version with the security fix

If immediate updating is not possible, consider implementing network-level controls to restrict the servers that the Hystrix Dashboard can communicate with, or temporarily disable the Hystrix Dashboard functionality until updates can be applied.
