high Nessus Plugin ID 103876
Language:
Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is affected by the following vulnerabilities :- A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
(CVE-2017-11780)
- A denial of service vulnerability exists in the Microsoft Server Block Message (SMB) when an attacker sends specially crafted requests to the server. An attacker who exploited this vulnerability could cause the affected system to crash. To attempt to exploit this issue, an attacker would need to send specially crafted SMB requests to the target system. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate their user rights, but it could cause the affected system to stop accepting requests. The security update addresses the vulnerability by correcting the manner in which SMB handles specially crafted client requests.
(CVE-2017-11781)
Note that Microsoft uses AC:H for these two vulnerabilities. This could mean that an exploitable target is configured in a certain way that may include that a publicly accessible file share is available and share enumeration is allowed for anonymous users.
Solution
Microsoft has released a set of patches for Windows 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, 10, and 2016.See Also
