Axxon One Default Password Login Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.2)

CVE-2026-121022

The vulnerability exists in a web client interface for a management product. Such web interfaces are frequently deployed as internet-facing portals to allow remote access for monitoring and management, making them commonly reachable in real-world network deployments.

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

External exposure likelihood

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability involves a default password in the web client of Axxon One, which could allow unauthorized remote access to newly installed systems. The main concern is confirming whether this specific product is in use and exposed.

  • Default passwords allow unauthorized remote access.
  • Confirm if this product is deployed and exposed.
  • Prioritize verifying its relevance to our environment.

Attack Path

How an attacker could exploit the issue

An attacker can access a newly installed system over the network and log in as the administrator without needing any credentials or user interaction. This is possible because the web client on the affected system does not require the default password to be changed upon first use, allowing an unauthenticated remote user to gain administrative access.

  • Remote, unauthenticated access to the web client.
  • Logging into the web client with default credentials.
  • Unauthorized administrative control of the system.

Live Threat

Current exploitation, exposure, and threat context

A remote, unauthenticated attacker could gain administrative access to a newly installed system via its web client. This occurs when the default administrator password is not changed upon initial setup.

  • Administrator credentials.
  • Default password not changed.
  • Unauthorized system control.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for the Axxon One product and its underlying operating systems (Windows/Linux) should prioritize addressing this vulnerability. The first practical step is to identify all deployed instances of the affected web client, confirm their external reachability, and determine the business criticality of each instance to establish a remediation priority.

  • Product and infrastructure teams own remediation.
  • Verify external reachability and business criticality first.
  • Plan immediate configuration review and password reset.

Frequently asked questions

What is Axxon One and what is it used for?

Axxon One is a security and video management software platform. Organizations use it to monitor surveillance cameras, manage video recording, and integrate various security sensors. It provides a central web-based interface for administrators to oversee these connected security operations on both Windows and Linux systems.

What does CVE-2026-121022 mean by Use of Default Password?

This vulnerability is classified as CWE-1393, which means the software ships with a built-in administrator account that uses a standardized, factory-set password. In this specific case, the web client fails to force a password change during the initial setup, leaving the system protected only by known, generic credentials that an unauthorized user could easily guess.

How does an attacker trigger this vulnerability?

An attacker targets a newly installed system that has not yet had its administrator password updated. By connecting to the system's web client over the network, they can log in using the factory default credentials. This vulnerability does not exist if the system was already configured with a custom, secure password immediately following the initial installation.

Is my system at risk if it is not internet-facing?

According to Halo Surface Signal, this vulnerability is particularly relevant to portals deployed as internet-facing interfaces for remote management. While systems restricted to internal, private networks face a lower immediate risk of external discovery, any system running the affected web client remains vulnerable if it has not undergone the mandatory password update process.

What are the first steps to secure my Axxon One deployment?

Your priority is to identify all active instances of the Axxon One web client across your infrastructure. Once identified, verify whether the default administrator password has been changed. If it remains at the default, perform a password reset immediately to secure the administrative account and prevent unauthorized access.
