## What is CVE-2025-5022?

CVE-2025-5022 is a medium-severity vulnerability in Mitsubishi Electric Corporation PV-DR004J, published on 10 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Weak Password Requirements 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 derive the password from the SSID. In addition, if the product is configured to enable the individual air conditioner control function, an attacker who has access to the Wi-Fi communication between the units by exploiting this vulnerability may be able to execute ECHONET Lite commands to perform operations such as turning the air conditioner on or off and changing the set temperature. The individual air conditioner control function is available only in display unit version 02.00.01 or later and measurement unit version 02.03.01 or later. The affected products discontinued in 2015, support ended in 2020.

Weakness: CWE-521 (Weak Password Requirements)

What it is: CVE-2025-5022 is a medium-severity vulnerability in Mitsubishi Electric Corporation PV-DR004J, published on 10 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-5022 in the wild and no public exploit code.

Affected product: Mitsubishi Electric Corporation PV-DR004J. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
