Title
Information Disclosure, Information Tampering, or Denial-of-Service (DoS) Vulnerability in Multiple Home Appliances
Summary
Use of Hard-coded Credentials vulnerability in Mitsubishi Electric Room Air Conditioners (for Japan and outside Japan); Wireless LAN Adapters for Room Air Conditioners (for Japan and outside Japan); Wireless LAN Adapters for Packaged Air Conditioners (for Japan and outside Japan); Refrigerators (for Japan); Heat Pump Water Heaters / HEMS-Compatible Adapters / Wireless LAN Adapters (for Japan); Bathroom Dryer / Heater / Ventilation Systems (for Japan); Adapters for Airflow Ventilation Systems, Heat Pump Chilled / Hot Water Systems, and Ventilation / Air-Conditioning System Air Resorts (for Japan); Lossnay Central Ventilation Systems (for Japan); Smart Switches for Ventilation Fans and Lossnay (for Japan); IH Cooking Heaters (for Japan); and Rice Cookers (for Japan) allows an attacker within Wi-Fi radio range of an affected product to access the affected product using a hard-coded SSID and password, thereby obtaining device data such as operation status, room set temperature, and room temperature; changing the air-conditioner or Wi-Fi settings; or causing Wi-Fi communication to enter a denial-of-service (DoS) condition.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
