Upstream source description

Nanosystems Supremo for Windows and macOS before 5.0.2.3874 contains an improper certificate validation vulnerability that allows adjacent attackers to intercept TLS connections by presenting untrusted certificates. Attackers on the same network can terminate and relay the client's TLS session using self-signed certificates to read usernames, SHA-256 password hashes, and license codes.
