Vodafone H500s WiFi Password Disclosure via activation.json

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.

A Command Injection vulnerability in httpd web server (setup.cgi) in SerComm h500s, FW: lowi-h500s-v3.4.22 allows logged in administrators to arbitrary OS commands as root in the device via the connection_type parameter of the statussupport_diagnostic_tracing.json endpoint.
