The default configuration of Terminal in Apple Mac OS X 10.6 before 10.6.7 uses SSH protocol version 1 within the New Remote Connection dialog, which might make it easier for man-in-the-middle attackers to spoof SSH servers by leveraging protocol vulnerabilities.

Security readout for executives and security teams

This issue affects Apple Mac OS X 10.6 before 10.6.7 when Terminal's New Remote Connection dialog defaults to SSH protocol version 1. That older protocol can make server spoofing easier in a man-in-the-middle situation. The practical concern is legacy Mac systems connecting to sensitive servers using weaker SSH behavior. Exposure is most likely on legacy Mac OS X 10.6 systems before 10.6.7, especially where users initiate SSH sessions through Terminal's New Remote Connection dialog. Modern macOS versions are not identified in the provided sources. Treat this as a legacy-system hygiene issue unless affected Macs still access sensitive infrastructure. If such systems remain, prioritize upgrade or isolation because the weakness can undermine trust in SSH server identity. Mitigation focus: Upgrade affected Mac OS X 10.6 systems to 10.6.7 or later.; Disable or avoid SSH protocol version 1 wherever configurable.; Follow Apple advisory guidance for Security Update 2011-001 or Mac OS X 10.6.7..
