Security Update for Microsoft Windows SMB Server (4013389)

Published: March 14, 2017

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker sends specially crafted messages to a Microsoft Server Message Block 1.0 (SMBv1) server.

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software and Vulnerability Severity Ratings section.

The security update addresses the vulnerabilities by correcting how SMBv1 handles specially crafted requests.

Vulnerability Information

Multiple Windows SMB Remote Code Execution Vulnerabilities

Remote code execution vulnerabilities exist in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerabilities could gain the ability to execute code on the target server.

To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server.

The security update addresses the vulnerabilities by correcting how SMBv1 handles these specially crafted requests.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

**Vulnerability title****CVE number****Publicly disclosed****Exploited**

### Mitigating Factors Microsoft has not identified any [mitigating factors](https://technet.microsoft.com/library/security/dn848375.aspx) for these vulnerabilities. ### Workarounds The following [workarounds](https://technet.microsoft.com/library/security/dn848375.aspx) may be helpful in your situation: - **Disable SMBv1** **For customers running Windows Vista and later** See [Microsoft Knowledge Base Article 2696547](https://support.microsoft.com/kb/2696547). **Alternative method for customers running Windows 8.1 or Windows Server 2012 R2 and later** For client operating systems: 1. Open **Control Panel**, click **Programs**, and then click **Turn Windows features on or off.** 2. In the Windows Features window, clear the **SMB1.0/CIFS File Sharing Support** checkbox, and then click **OK** to close the window. 3. Restart the system. For server operating systems: 1. Open **Server Manager** and then click the **Manage** menu and select **Remove Roles and Features**. 2. In the Features window, clear the **SMB1.0/CIFS File Sharing Support** check box, and then click **OK** to close the window. 3. Restart the system. **Impact of workaround.** The SMBv1 protocol will be disabled on the target system. **How to undo the workaround.** Retrace the workaround steps, and select the **SMB1.0/CIFS File Sharing Support** check box to restore the SMB1.0/CIFS File Sharing Support feature to an active state. Windows SMB Information Disclosure Vulnerability – CVE-2017-0147 ---------------------------------------------------------------- An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server. To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server. The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests. The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

If you stumbled upon this post you most certainly know about the recent Ransomware called Ransom:Win32/WannaCrypt, better known as WannaCry, and you want to know if your system is immune to it. To keep it short, there’s a high chance you already are… as long as you patched your OS on regular basis. The SMB Vulnerability Jump which has been exploited by WannaCry/WannaCrypt has been patched since March 2017 and distribuited through the standard Windows Update feature.

If you didn’t patch – as most international companies who have been impacted – you should really spend some valuable time in doing that just now by going to the official Technet resource page for MS17-010 Jump. There you will find all patches for all Windows versions including Windows 10, Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows Server 2012 R2 and Windows Server 2016.

Wannacry patch for windows xp

As soon as you did that, you might also want to do the following, as suggested by this other Technet blog post:

  • Check if your system is protected using this Powershell script in order to ensure that you performed the update properly.
  • Block SMB incoming connections (Port 445) from External – Internal Network on Edge Firewalls
  • Upgrade legacy systems to latest OS (Windows 10 , Better Inbuilt protections – Credential Guard, Device Guard, Memory Protections, Secure Kernel, VBS, Edge Browser etc).
  • Microsoft just released emergency security updates/fixes for legacy systems as well (Windows XP , Server 2003 etc). Download links are below (and also in the aforementioned Technet page).

For additional technical info about the malware, I can only suggest reading the following posts from MMPC, FireEye and Technet:

And these are the links for legacy systems:
