Publication date: 2026-03-23

Last updated on: 2026-04-29

Assigner: 309f9ea4-e3e9-4c6c-b79d-e8eb01244f2c

Description
Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 does not implement CSRF protections on state-changing endpoints such as /goform/setSysTools and other administrative interfaces. As a result, an attacker can craft malicious web requests that are executed in the context of an authenticated administrator’s browser, leading to unauthorized configuration changes, including enabling services or modifying system settings.

Executive Summary

The vulnerability exists in Nexxt Solutions Nebula 300+ firmware versions up to 12.01.01.37, where there is no Cross-Site Request Forgery (CSRF) protection on state-changing administrative endpoints.

This means a remote attacker can trick an authenticated administrator into submitting crafted requests that change device settings without the administrator's knowledge or intent.

Impact Analysis

This vulnerability can allow an attacker to modify important device settings, including security-related configurations, by exploiting the lack of CSRF protections.

Such unauthorized changes could compromise the security and proper functioning of the device, potentially leading to further exploitation or loss of control.
