CVE-2025-5023: 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.
The exploitability of CVE-2025-5023 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2025-5023 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-5023, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-5023, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
