Microsoft released an urgent security update earlier to block a security vulnerability that was accidentally leaked a few days ago. The vulnerability exists in all 32-bit and 64-bit versions of Windows 10, including client and server, and utilizes a protocol called “Server Message Block”.
As long as the attacker obtains the control of either the client or the server, the client can control the server to execute the program code through a special packet, or if the attacker controls the server, the client can connect to the server Execute the program code on the client.
Because this vulnerability can allow malicious programs to be distributed within the company through the intranet, Microsoft considers it to be a very serious vulnerability.
Although Windows 10 has a certain protection mechanism, it has not yet come out of the disaster. But I still hope that you can install new patches as soon as possible.
General users should be able to obtain the KB4551762 security update directly through Windows Update.
