Deeper analysis
The vulnerability CVE-2023-51587 is a missing authentication flaw in the getModbusPassword method of Voltronic Power ViewPower. It affects installations of this power management software and permits remote information disclosure without requiring any credentials, as the method fails to enforce authentication before exposing functionality.
An unauthenticated remote attacker can exploit the issue over the network to retrieve stored credentials, which may then be used to achieve further compromise. The vulnerability received a CVSS v3 score of 7.5 and is tracked under CWE-306.
The Zero Day Initiative published advisory ZDI-23-1892 detailing the flaw, originally reported as ZDI-CAN-22073. The EPSS score has remained flat at a peak of 0.0812 with no material increase observed after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
