Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Applies to: Windows Server , Windows 10, Windows 8. While disabling or removing SMBv1 might cause some compatibility issues with old computers or software, SMBv1 has significant security vulnerabilities and we strongly encourage you not to use it. We recommend keeping SMBv2 and SMBv3 enabled, but you might find it useful to disable one temporarily for troubleshooting. In Windows 10, Windows 8.
Here are the steps to detect, disable and enable SMBv1 client and server by using PowerShell commands. This behavior occurs because these protocols share the same stack.

Internet Explorer and Edge are exploitable. Attack via web application vulnerability SecureWorks researchers also identified the attack vector can be used in combination with web application vulnerabilities. For example. Figure 8 presents PHP code demonstrating the DoS exploit using “unvalidated redirects” vulnerability. Figure 11 presents the HTTP request from the browser. The response includes a redirection to SMB. Other web application vulnerabilities such as cross-site scripting XSS.
HTTP header injection can be used as well. Conclusion SecureWorks analysis indicates that SMB zero-day attacks can be performed using web application vulnerabilities such as cross-site scripting XSS. HTTP header injection. SecureWorks researchers recommend that users quickly apply the March Windows Update after it is released. As a temporary measure. Request compounding – allows for sending multiple SMB 2 requests as a single network request Larger reads and writes – better use of faster networks Caching of folder and file properties – clients keep local copies of folders and files Durable handles – allow for connection to transparently reconnect to the server if there is a temporary disconnection Improved message signing – HMAC SHA replaces MD5 as hashing algorithm Improved scalability for file sharing – number of users.
Windows 8. Windows Windows Server Windows Server R2. Transparent Failover – clients reconnect without interruption to cluster nodes during maintenance or failover Scale Out — concurrent access to shared data on all file cluster nodes Multichannel – aggregation of network bandwidth and fault tolerance if multiple paths are available between client and server SMB Direct — adds RDMA networking support for very high performance.
