CVE-2026-31928 in VFC-DMP-5000
Summary
by MITRE • 06/27/2026
The DMP-5000 devices are shipped with a default administrative web account with weak authentication controls, which are not required to be changed during initial configuration or operation. Using these accounts provides full system access.

The DMP-5000 device vulnerability represents a critical security flaw that stems from improper default credential management and insufficient authentication mechanisms. This issue directly violates fundamental security principles outlined in the CWE catalog under category 798 which specifically addresses the use of hard-coded credentials. The device ships with pre-configured administrative accounts that lack strong authentication controls, creating an inherent risk that persists throughout the device lifecycle without requiring any configuration changes from administrators. These default credentials remain active and accessible by default, providing attackers with immediate privileged access to the entire system infrastructure.
The technical implementation flaw lies in the device firmware design where administrative accounts are provisioned with predictable usernames and passwords that are either publicly documented or easily guessable. This weakness enables unauthorized users to bypass all normal authentication mechanisms and gain complete control over the device's operational capabilities. The vulnerability exists at the authentication layer and represents a failure in the principle of least privilege, as the default administrative accounts provide full system access without requiring additional verification steps or account modifications. According to ATT&CK framework domain T1078, adversaries exploit default accounts as a primary technique for gaining initial access and maintaining persistent presence within target environments.
The operational impact of this vulnerability is severe and far-reaching across multiple security domains. Once exploited, attackers can manipulate device configurations, extract sensitive data, modify network settings, and potentially use the compromised device as a pivot point for further attacks within the network. The persistence of these default credentials means that even if administrators are aware of the issue, they may not realize the extent of exposure until after an attack has occurred. This vulnerability undermines the integrity of the entire security posture by providing a backdoor access method that bypasses all normal security controls and monitoring mechanisms. Organizations deploying these devices face increased risk of data breaches, system compromise, and potential regulatory violations due to inadequate security configurations.
Effective mitigation strategies must include immediate credential rotation upon device deployment, implementation of strong password policies, and regular security assessments to identify any persistent default accounts. Administrators should enforce mandatory account configuration during initial setup procedures and establish automated monitoring for unauthorized access attempts. The vulnerability highlights the importance of following security guidelines from NIST SP 800-123 and other industry standards that emphasize the need for secure configuration management. Organizations must also implement network segmentation controls to limit the potential impact of compromised devices and establish incident response procedures specifically addressing default credential exploitation scenarios. Regular firmware updates and vulnerability scanning processes should be implemented to ensure that any newly discovered default credential issues are addressed promptly.
