Official description
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 underlying weakness: Use of Default Credentials
The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.
How developers prevent this class of flaw
- Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
- Force the administrator to change the credential upon installation.
- The product administrator could change the defaults upon installation or during operation.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
