Description

Use of Hard-coded Credentials vulnerability in Mitsubishi Electric Corporation photovoltaic system monitor “EcoGuideTAB” PV-DR004J all versions and PV-DR004JA all versions allows an attacker within the Wi-Fi communication range between the units of the product (measurement unit and display unit) to disclose information such as generated power and electricity sold back to the grid stored in the product, tamper with or destroy stored or configured information in the product, or cause a Denial-of-Service (DoS) condition on the product, by using hardcoded user ID and password common to the product series obtained by exploiting CVE-2025-5022. However, the product is not affected by this vulnerability when it remains unused for a certain period of time (default: 5 minutes) and enters the power-saving mode with the display unit's LCD screen turned off. The affected products discontinued in 2015, support ended in 2020.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Use of Hard-coded Credentials

The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. Learn more on MITRE.
