<< Back VID 26825 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description Microsoft Security Update for December 2018 is not installed. - A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. (CVE-2018-8540) - An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. (CVE-2018-8595, CVE-2018-8596) - 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-2018-8631) - An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8639) - 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-2018-8477) - An information disclosure vulnerability exists when Remote Procedure Call runtime improperly initializes objects in memory. (CVE-2018-8514) - An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2018-8611) - A remote code execution vulnerability exists in the way that the VBScript engine handles 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-2018-8625) - A remote code execution vulnerability exists when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. An attacker who exploited the vulnerability could run arbitrary code with medium-integrity level privileges (the permissions of the current user). (CVE-2018-8619) * 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 Recommendation Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin December 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.
