Hard-coded Credentials in Care Everywhere Gateway Allow Remote Code Execution via WildFly

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-41939

The vulnerability resides in a management interface of a gateway product. While gateway management consoles are ideally restricted to internal networks, they are frequently misconfigured or exposed to the public internet in common real-world deployments to allow for remote administration.

Remote Code Execution

Horizon Alert

Summary of the vulnerability and why it matters

This critical vulnerability involves hard-coded credentials in a gateway product, potentially allowing unauthenticated remote attackers to gain administrative control and execute malicious code. The affected component is an outdated, end-of-life product, but it's important to confirm if your environment uses this technology or similar configurations, as such systems can be attractive targets for compromise.

Default credentials grant remote administrative access.
Outdated gateway technology poses a significant risk.
Confirm relevance and exposure to avoid potential compromise.

Attack Path

How an attacker could exploit the issue

An attacker can exploit a hard-coded credentials vulnerability in the WildFly management interface of the Care Everywhere Gateway. This allows unauthenticated remote attackers to access the management console using default credentials. From there, they can deploy a malicious file to gain administrative access and execute code as the machine account.

No authentication required.
Deploying a malicious file.
Remote code execution.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, unauthenticated remote attackers could gain administrative access to the Care Everywhere Gateway's WildFly management interface. This access could allow for the deployment of malicious files, leading to remote code execution.

System data and services at risk.
Malicious file deployment via management interface.
Remote code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability impacts the Care Everywhere Gateway's WildFly management interface. Responsibility likely falls to application owners or platform teams managing the gateway, with potential involvement from infrastructure and security teams for broader network exposure and remediation planning. The first practical step is to identify all instances of the affected technology, confirm network reachability and business criticality, and then assign ownership for coordinated remediation.

Assign issue ownership to the application or platform team.
Verify external reachability and business criticality.
Plan remediation and coordinate with the vendor.

Frequently asked questions

What is the Care Everywhere Gateway?

Care Everywhere Gateway is a specialized software product designed for data interoperability and secure communication in environments like healthcare. It often incorporates third-party infrastructure components, such as the WildFly application server, to manage services and connectivity. Because this specific technology reached its end-of-life in 2017, it is no longer updated or supported by the vendor to address modern security challenges.

What does hard-coded credentials mean for CVE-2026-41939?

This vulnerability, classified as CWE-1392, means the software was shipped with permanent, unchangeable login information embedded directly into its management interface. Because these default credentials are identical across every installation of the software, an attacker who knows them can bypass standard login security, granting them full administrative control without needing to crack a password or perform any typical authentication.

How do attackers trigger this vulnerability?

An attacker triggers this issue by connecting to the WildFly management console on port 20990 and providing the known default credentials. Once logged in, they can use the built-in deployment features to upload and execute malicious files. Importantly, this process does not require any prior user interaction, specific permissions, or complex hacking techniques; the system simply accepts the default credentials as valid authority.

Why should I care if my gateway is exposed?

Halo Surface Signal indicates that management consoles for gateways are frequently misconfigured, leading to unintended exposure on the public internet. If your interface is reachable outside your internal network, attackers can identify and target your system remotely. Even in internal-only environments, this vulnerability allows any user on the network to escalate their access to full system control.

How should I respond to this threat?

Your first step is to conduct an inventory to locate all instances of Care Everywhere Gateway within your infrastructure. Once identified, verify whether the management interface is accessible from the network. Because the product is end-of-life, prioritize migrating away from this technology to a supported, modern alternative. If immediate removal is not possible, strictly restrict network access to the management console to prevent unauthorized connections.
