CVE-2026-41939 in Gateway
Summary
by MITRE • 07/29/2026
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.

The Care Everywhere Gateway version 14.3.10 presents a critical security vulnerability through its embedded WildFly 8.2.0.Final application server management interface. This vulnerability stems from hard-coded credentials that are identical across all installations, creating a universal attack vector for unauthenticated remote adversaries. The flaw exists within the management console exposed on port 20990, which serves as an entry point for malicious actors seeking administrative privileges. This configuration violates fundamental security principles by providing default authentication mechanisms that remain unchanged regardless of deployment environment or security requirements.
The technical implementation of this vulnerability aligns with CWE-798, which identifies the use of hard-coded credentials as a significant security weakness. The embedded WildFly management interface operates with predetermined username and password combinations that have not been altered from their original defaults, eliminating any possibility for administrators to implement proper authentication controls. This design flaw creates an immediate path to administrative access without requiring any prior knowledge of system-specific credentials or successful exploitation of other vulnerabilities. The exposed port 20990 serves as the primary attack surface where remote attackers can establish connections and begin the exploitation process.
The operational impact of this vulnerability extends beyond simple unauthorized access, creating a complete compromise scenario for affected systems. Once authenticated through the management console, attackers can leverage the Deployments interface to upload and deploy malicious Web Application Archive files, effectively enabling remote code execution capabilities. This privilege escalation allows adversaries to execute arbitrary code as the Windows machine account, providing them with elevated system-level access that can be used for further lateral movement within networks or data exfiltration activities. The vulnerability essentially transforms any exposed Care Everywhere Gateway installation into a potential command and control node for broader attack operations.
Security professionals should recognize this issue as a classic example of the ATT&CK technique T1078.004, which involves legitimate credentials use to maintain persistent access to systems. The hard-coded nature of these credentials means that attackers can maintain long-term access without detection, as no system logs would indicate credential compromise through normal authentication mechanisms. Organizations should implement immediate mitigation strategies including network segmentation to isolate exposed management interfaces, disabling unnecessary services where possible, and implementing proper access controls using firewalls or network access control lists to restrict access to port 20990. The fact that version 14.x.x reached end-of-life in 2017 emphasizes the importance of maintaining current software versions and addressing known vulnerabilities through proper patch management processes.
