Advantech WebAccess 8.3.4 does not properly restrict an RPC call that allows unauthenticated, remote users to read files. An attacker can use this vulnerability to recover the administrator password.
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
