Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Care Everywhere Gateway 14.3.10 contains a hard-coded credentials vulnerability in the bundled WildFly 8.2.0.Final management interface that allows unauthenticated remote attackers to gain administrative access by using default credentials identical across all installations. Attackers can authenticate to the exposed WildFly management console on port 20990 and deploy a malicious Web Application Archive file through the Deployments interface to achieve remote code execution as the Windows machine account. Version 14.x.x was declared end-of-life (EOL) in 2017 and future releases have addressed the vulnerable finding.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Care Everywhere Gateway 14.3.10 bundles WildFly 8.2.0.Final with hard-coded default credentials in its management interface on port 20990. Unauthenticated remote attackers can leverage these identical credentials across all installations to access the WildFly admin console, upload and deploy malicious WAR files, and achieve remote code execution as the Windows machine account.

MitigationUpgrade from EOL version 14.x to a supported release that addresses this finding. As an interim control, block external access to port 20990 at the network perimeter until the upgrade is completed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Care Everywhere Gateway installation
    Look for the Care Everywhere Gateway installation directory (commonly in Program Files or a dedicated application folder) and check for running processes named 'CareEverywhereGateway' or similar
    Affected if Care Everywhere Gateway is installed and the installation cannot be verified as a post-vulnerable version
  2. Check installed version
    Locate version information in the installation directory (typically in a version.txt, about dialog, or configuration files) and compare to 14.3.10
    Affected if Installed version is 14.3.10 or lower (pre-fix version)
  3. Verify bundled WildFly version
    Within the Care Everywhere Gateway installation directory, locate the WildFly subdirectory and check the version file or jar manifest for '8.2.0.Final'
    Affected if Bundled WildFly version is 8.2.0.Final
  4. Check if management port 20990 is listening
    Run 'netstat -an | findstr 20990' or 'Get-NetTCPConnection -LocalPort 20990' to determine if the WildFly management interface port is open and listening
    Affected if Port 20990 is in LISTENING state on any interface
  5. Verify network exposure of port 20990
    Confirm port 20990 is bound to non-localhost interfaces (0.0.0.0 or external IP rather than 127.0.0.1) indicating the management interface is network-accessible
    Affected if Port 20990 is listening on 0.0.0.0 or an external IP address rather than localhost only

Environment is affected if Care Everywhere Gateway version 14.3.10 or lower (with WildFly 8.2.0.Final) is installed AND port 20990 is exposed on the network, enabling unauthenticated attackers to reach the management interface with default credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade from EOL version 14.x to a supported release that addresses this finding. As an interim control, block external access to port 20990 at the network perimeter until the upgrade is completed.

Recommended fix Moderate confidence

Contact vendor for specific supported version (14.x was EOL in 2017; newer releases contain the fix)

  1. 1. Contact NextGen Healthcare or the Care Everywhere Gateway vendor to obtain the specific fixed release version that addresses CVE-2026-41939
  2. 2. Request documentation on the migration path from the EOL 14.x version to a supported release
  3. 3. Before upgrading, perform a complete backup of the Care Everywhere Gateway system and database
  4. 4. Schedule a maintenance window as the upgrade will likely require downtime
  5. 5. Upgrade the Care Everywhere Gateway to the vendor-specified supported version that includes the fix for hard-coded credentials in WildFly
  6. 6. After upgrade, verify that the WildFly management console (port 20990) is either disabled, bound to localhost only, or protected with strong non-default credentials
  7. 7. Change any default passwords that may have been present in the WildFly or application configuration
  8. 8. Test all critical workflows to ensure the upgrade did not break existing functionality
Caveat Upgrading from EOL 14.x to a current supported version may require migration procedures and could introduce compatibility changes with integrated systems
