Neutron Smart VMS is a local client-side application used for managing security cameras. It is normally deployed within isolated, private local CCTV networks and has no typical public internet exposure.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability in Neutron Smart VMS allows an attacker to bypass authentication, meaning they could gain unauthorized access to the system. This is critical because it compromises the security and integrity of the video surveillance data managed by the affected software.

  • Unauthorized access to video feeds.
  • Could affect organizations using this VMS.
  • Attacker bypasses login controls.

Attack Path

How an attacker could exploit the issue

An attacker can bypass authentication for the Neutron Smart VMS system without any prior access or user interaction. This flaw allows them to gain unauthorized control over the video management system.

  • Network access required.
  • Target: Neutron Smart VMS.
  • Bypass authentication.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability allows for an authentication bypass without any privileges, making it an attractive target for attackers. The critical severity and potential for full system compromise suggest it could be widely weaponized. However, the limited scope of the affected product, Neutron Smart VMS, may restrict its broad applicability.

  • Exploitation appears unobserved.
  • Public exploit code is not readily available.
  • The CVE was published in September 2023.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Given the CRITICAL severity and potential for authentication bypass, prioritize identifying and isolating any Neutron Smart VMS instances accessible from the internet or untrusted networks. Focus on patching these systems immediately, as the exploit is straightforward and requires no user interaction.

  • Patch to version b1130.1.0.1 or later.
  • Isolate affected systems if patching is delayed.
  • Monitor network traffic for suspicious access attempts.

Frequently asked questions

What is Neutron Smart VMS and its purpose?

Neutron Smart VMS is a video management system designed for the effective management of security cameras. It enables organizations to oversee and manage their video surveillance data efficiently.

How does CVE-2023-4178 enable an attacker to bypass security?

CVE-2023-4178 is an Authentication Bypass by Spoofing vulnerability. An attacker can exploit this by deceiving the Neutron Smart VMS into recognizing them as a legitimate user, thereby granting them unauthorized entry.

What is required for an attacker to exploit this vulnerability?

An attacker can bypass the authentication controls for the Neutron Smart VMS system. This bypass does not require any prior access or interaction from a user.

What is the relevance of CVE-2023-4178 according to Halo Surface Signal?

Halo classifies this CVE as external due to its CVSS v3.1 Attack Vector being Network. However, Halo's assessment indicates it is 'Very unlikely' to be exploited as Neutron Smart VMS is typically a local client-side application deployed in isolated, private CCTV networks with no typical public internet exposure.

What steps should be taken to address this vulnerability?

To address this critical vulnerability, organizations should immediately identify and isolate any Neutron Smart VMS instances accessible from the internet or untrusted networks. Prioritize patching these systems to version b1130.1.0.1 or later. If patching is delayed, continued isolation and monitoring of network traffic for suspicious access attempts are advised.
