External exposure likelihood

Horizon Alert

Summary of the vulnerability and why it matters

An exposed endpoint in Ivanti Neurons Patch for Intune may allow a remote attacker to access sensitive authentication information. This could potentially impact the confidentiality and integrity of the system.

  • Sensitive information can be leaked.
  • Authentication data exposure is a serious risk.
  • Confirm relevance and assess potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker with valid credentials can leverage a dangerous endpoint exposed by Ivanti Neurons Patch for Intune to steal sensitive authentication details. This could potentially allow them to gain further unauthorized access to systems.

  • Requires authenticated access.
  • Targets a dangerous endpoint.
  • Leads to sensitive information disclosure.

Live Threat

Current exploitation, exposure, and threat context

A dangerous endpoint in Ivanti Neurons Patch for Intune could allow a remote attacker, who has already authenticated to the system, to leak sensitive authentication information. This exposure may occur when the supported conditions for the vulnerability are met.

  • Authentication credentials may be leaked.
  • An authenticated attacker could exploit it.
  • Unspecified authentication information could be exposed.

Operational Fix

Recommended remediation, mitigation, and detection steps

In production environments, the Platform Engineering or Infrastructure teams are likely responsible for Ivanti Neurons Patch for Intune, with Security Operations needing to confirm exposure. The first step is to locate all instances of Ivanti Neurons Patch for Intune, assess their reachability and business criticality, identify the accountable owner, and then prioritize remediation efforts based on the associated risk.

  • Platform or Infrastructure teams own remediation.
  • Verify external reachability and asset criticality first.
  • Plan remediation based on exposure and business impact.

Frequently asked questions

What is Ivanti Neurons Patch for Intune?

It is an enterprise tool designed to simplify software updates and security patching for organizations using Microsoft Intune. By bridging internal system management with cloud-based device administration, it helps IT teams automate the delivery of updates across managed environments, ensuring that software stays current and configurations remain consistent.

What does CWE-749 mean for CVE-2026-109412?

This vulnerability involves an exposed dangerous method or endpoint, which is a flaw where a software interface accidentally allows users to trigger powerful actions or access data they shouldn't. In this case, the flaw creates a path for an attacker to extract sensitive authentication credentials that the system is intended to protect.

Does this vulnerability trigger automatically?

No. The flaw is not triggered by simply connecting to the network or browsing the site. It requires the attacker to already have valid credentials to authenticate to the system. Once authenticated, they must specifically interact with the vulnerable endpoint to successfully leak the protected authentication information.

Is my instance reachable from the internet?

Halo Surface Signal indicates this product is often part of edge-facing administrative infrastructure that bridges internal and cloud systems. Because it frequently interfaces with external APIs and cloud services, you should verify if your specific instance is directly accessible via the internet or if it is restricted to internal network traffic.

How should I respond to this advisory?

Begin by identifying all deployments of the software within your infrastructure and determining who owns each instance. Assess the business criticality and network reachability of these assets. Once you have a clear map of your environment, coordinate with your platform or infrastructure teams to prioritize remediation according to your organization's risk management policies.
