AI-suggested

Upgrade Szafir to version 2.0 build 708 or later, where the certificate and hostname validation issue is fixed. No other mitigation is indicated by the vendor advisory.

Description

Szafir versions prior to 2.0 build 708 accept any client or server certificate without validating the certificate or hostname. This allows HTTPS connections without authenticating the remote server, enabling an attacker to present arbitrary SSL/TLS certificates and potentially cause the application to download malicious update files from their server. The vulnerability is fixed in version 2.0 build 708.
