"To exploit the vulnerability against an SMB Server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 Server. To exploit the vulnerability against an SMB Client, an unauthenticated attacker would need to configure a malicious SMBv3 Server and convince a user to connect to it." Unlike the Microsoft Windows SMB Server flaws used by the EternalBlue and EternalRomance exploits, which were leveraged for the 2017 WannaCry and NotPetya outbreaks, CVE-2020-0796 only affects SMBv3 and does not affect Windows 7 and Windows Server 2008 R2 systems.
