<< Back VID 26823 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description Microsoft Security Update for October 2018 is not installed. - A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2018-8460, CVE-2018-8491) - A security feature bypass vulnerability exists in DNS Global Blocklist feature. An attacker who successfully exploited this vulnerability could redirect traffic to malicious DNS endpoints. The update addresses the vulnerability by updating DNS Server Role record additions to not bypass the Global Query Blocklist. (CVE-2018-8320) - An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2018-8330) - A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system. (CVE-2018-8432) - An information disclosure vulnerability exists when DirectX improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how DirectX handles objects in memory. (CVE-2018-8486) - An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. (CVE-2018-8472) - A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2018-8489) - An elevation of privilege vulnerability exists when NTFS improperly checks access. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2018-8411) - A remote code execution vulnerability exists when the Microsoft XML Core Services MSXML parser processes user input. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the users system. (CVE-2018-8494) * Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts. * References: https://support.microsoft.com/en-us/help/4009469 https://support.microsoft.com/en-us/help/4009470 https://support.microsoft.com/en-us/help/4009471 https://support.microsoft.com/en-us/help/4000825 * Platforms Affected: Windows Server 2008 SP2 Windows Server 2008 x64 SP2 Windows 7 SP1 Windows 7 x64 SP1 Windows Server 2008 R2 SP1 Windows Server 2008 R2 x64 SP1 Windows 8.1 Windows Server 2012 Windows Server 2012 R2 Windows 10 Windows Server 2016 Recommendation Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin October 2018 Microsoft security update at https://support.microsoft.com/en-us/help/4009469 https://support.microsoft.com/en-us/help/4009470 https://support.microsoft.com/en-us/help/4009471 https://support.microsoft.com/en-us/help/4000825 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com.
