Description
SmsForwarder through 3.5.0 contains a missing authentication vulnerability in its AndServer HTTP server that allows unauthenticated network attackers to invoke remote-control APIs. Attackers can call the default-enabled endpoints to read SMS, call logs and contacts, send SMS, and export or overwrite configuration via the clone API.
