CVE-2022-4985Public exploitNetwork attack vector

WiFi password disclosure via unauthenticated activation endpoint

Published Nov 14, 2025 · Updated Nov 14, 2025

Information disclosure in Vodafone H500s firmware 3.5.10 and earlier allows remote attackers to read the WiFi password over HTTP. The /data/activation.json handler returns a JSON wifi_password value after a crafted GET request with specific headers and a pageid cookie, without authenticating the requester. Network access to the router's HTTP service is the reported gate; disclosure exposes the configured credential without altering router data or availability.
