CVE-2025-57441 is a critical-severity flaw (CVSS 9.8) affecting atem mini pro firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Blackmagic ATEM Mini Pro 2.7 exposes sensitive device and stream configuration information via an unauthenticated Telnet service on port 9990. Upon connection, the attacker can access a protocol preamble that leaks the video mode, routing configuration, input/output labels, device model, and even internal identifiers such as the unique ID. This can be used for reconnaissance and planning further attacks.
