Security News > 2020 > March > Microsoft releases patch for leaked SMBv3 RCE flaw

After the inadvertent leaking of details about a wormable Windows SMBv3 RCE flaw on Tuesday, Microsoft has rushed to release a patch.

The flaw affects Windows 10 and Windows Server installations, so admins who have those in their care are urged to implement the security updates right away.

"A network based attack can compromise any Windows computer that has file sharing enabled, whether that machine is just a standard desktop or a more robust file server," SophosLabs researchers have pointed out.

Finally, an inside attacker could exploit the flaw to give themselves SYSTEM privileges - after having gained code execution on the targeted machine.

The #SMB bug appears trivial to identify, even without the presence of a patch to analyze.
