AI-analyzed exploit summary This exploit discloses the WiFi password of Vodafone H-500-s routers by sending a crafted GET request to the /data/activation.json endpoint with specific headers and cookies. The password is extracted from the JSON response.

Description

Vodafone H500s devices running firmware v3.5.10 (hardware model Sercomm VFH500) expose the WiFi access point password via an unauthenticated HTTP endpoint. By sending a crafted GET request to /data/activation.json with specific headers and cookies, a remote attacker can retrieve a JSON document that contains the wifi_password field. This allows an unauthenticated attacker to obtain the WiFi credentials and gain unauthorized access to the wireless network, compromising confidentiality of network traffic and attached systems.
