Technical Analysis

This vuln. appears to allow any authenticated user on a Windows system to modify the configuration settings for OpenSSH, which would allow for configuring it in such a way that could allow for a privilege escalation for an inbound user via SSH. OTOH, if you are already authenticated, you could just login yourself and perform an LPE much the same way as SMBGhost was used for LPE CVE-2020-0796
