Official description
A TLS vulnerability exists in the phone application used to manage a connected device. The phone application accepts self-signed certificates when establishing TLS communication which may result in man-in-the-middle attacks on untrusted networks. Captured communications may include user credentials and sensitive session tokens.

The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
