Radiometrics VizAir Lacks Authentication for Critical Functions

CVE advisorySeverity: CRITICAL (CVSS 10.0)

CVE-2025-61956

Radiometrics VizAir is an aviation and meteorological monitoring system. While these systems often operate within restricted or internal aviation infrastructure networks, they may be reachable via management interfaces or integrated API endpoints in some environments. Public internet exposure is not the standard design for this product type, making it possible but not inherently public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in Radiometrics VizAir could allow unauthorized modification of critical functions, potentially affecting runway settings and meteorological data, which could mislead air traffic control and pilots. The main concern is confirming relevance and exposure.

  • Unauthorized changes could impact flight operations.
  • Critical aviation systems require diligent oversight.
  • Assess if your systems are affected.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by accessing the Radiometrics VizAir system over a network without needing any credentials. Once access is gained, they could manipulate critical functions. This manipulation could lead to incorrect runway assignments for aircraft or the dissemination of false weather information, significantly impacting air traffic safety.

  • No authentication required for access.
  • Attacker triggers vulnerability by accessing critical functions.
  • Risk includes misleading air traffic and flight planning.

Live Threat

Current exploitation, exposure, and threat context

An attacker could manipulate critical functions of Radiometrics VizAir without authentication. This could lead to altered runway settings, which may mislead air traffic control and pilots, or affect meteorological data used for flight planning and weather forecasting.

  • Critical system configurations.
  • Unauthenticated API or admin access.
  • Misleading air traffic control.

Operational Fix

Recommended remediation, mitigation, and detection steps

Systems managing aviation and meteorological data, like Radiometrics VizAir, are typically owned by specialized infrastructure or platform teams within aviation authorities or weather services. The first actionable step is to locate all instances of this technology, verify their business criticality and network exposure, identify the accountable owner, and then prioritize remediation based on assessed risk.

  • Infrastructure/Platform Teams own the issue.
  • Verify system exposure and criticality first.
  • Plan remediation after ownership confirmation.

Frequently asked questions

What is Radiometrics VizAir?

Radiometrics VizAir is an aviation and meteorological monitoring system. It is designed to assist aviation authorities and weather services by managing critical runway configuration settings and processing meteorological data used for flight planning and air traffic control operations.

What does CWE-306 mean for CVE-2025-61956?

CWE-306 refers to a missing authentication for critical function vulnerability. In the context of CVE-2025-61956, this means the software does not verify the identity of a user before allowing access to administrative tools or API requests, essentially letting anyone with network access perform sensitive actions.

How can an attacker trigger this vulnerability?

An attacker can trigger this flaw by accessing the VizAir system over a network and interacting directly with its critical functions or API endpoints without needing to provide any login credentials. The bug is triggered by the lack of gatekeeping; it is not dependent on specific user actions, file uploads, or complex sequences.

Is my VizAir system at risk?

According to Halo Surface Signal, risk depends on your network environment. While these systems are usually intended for internal or restricted aviation infrastructure, they may be reachable if management interfaces or APIs are accidentally exposed. You should determine if your specific instance is accessible via the network where an unauthorized party could reach it.

How should I respond to this threat?

Begin by identifying every instance of VizAir within your network to confirm where it is deployed. Once located, verify the current network exposure and business criticality of each system. Coordinate with the platform or infrastructure owners to confirm ownership and establish a plan for remediation, prioritizing systems that have the widest connectivity.
