Halo Surface Signal score for CVE-2019-1405

This vulnerability affects a local Windows service and requires the attacker to already have local access to the system to exploit. It does not provide a mechanism for remote, internet-based exploitation, as the affected COM object creation process is inherently local to the host operating system.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in the Windows Universal Plug and Play (UPnP) service could allow an attacker with local access to gain elevated privileges. This flaw stems from an improper handling of COM object creation within the service. Successful exploitation could result in an attacker gaining administrative control over the affected system.

  • Vulnerable: Windows UPnP service
  • Flaw: Improper COM object creation
  • Impact: Elevated system privileges

Attack Path

How an attacker could exploit the issue

This vulnerability allows an attacker with local access to elevate their privileges on a Windows system. The Windows Universal Plug and Play (UPnP) service has a weakness in how it handles the creation of COM objects. This flaw can be exploited to gain higher access levels than initially possessed. This could lead to unauthorized actions or data access on the affected system.

  • Local user requires access.
  • Attacker creates COM objects.
  • Attacker gains elevated control.

Frequently asked questions

What is the Windows Universal Plug and Play (UPnP) service?

The Windows Universal Plug and Play (UPnP) service is a component of the Windows operating system that enables devices on a network to discover and connect with each other automatically. It's often used for things like setting up printers or media devices without manual configuration.

What kind of weakness is CVE-2019-1405?

CVE-2019-1405 is an elevation of privilege vulnerability. This means that a user with limited access on a system could exploit this flaw to gain administrative control over that system.

What must an attacker do to exploit CVE-2019-1405?

An attacker must first have local access to the affected Windows system. The vulnerability is not triggered remotely, meaning the attacker needs to be able to run code or interact directly with the machine.

Who should be concerned about CVE-2019-1405?

Any organization running affected versions of Windows should be concerned. The Halo Surface Signal indicates this vulnerability is internal, meaning it requires local access to exploit, but elevated privileges can still impact sensitive data or system operations.

What's the first step to address CVE-2019-1405?

The first step is to identify all Windows systems that might be running the affected UPnP service. Once identified, organizations should apply any available updates or patches provided by Microsoft to remediate the vulnerability.
