Attack-Flow Graph

Executive Summary

This vulnerability is caused by improper input validation in the gateway health check feature of Devolutions Server. It allows a low-privileged authenticated user to perform server-side request forgery (SSRF) by sending a specially crafted API request.

SSRF means the attacker can make the server send requests to internal or external systems that the attacker normally could not access directly.

Impact Analysis

The vulnerability can lead to information disclosure because an attacker can use SSRF to access sensitive internal resources or data through the server.
