<< Back VID 26844 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description Microsoft Security Update for June 2020 is not installed. - An elevation of privilege vulnerability exists in the way that the wlansvc.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1270) - 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-2020-1348) - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2020-1281) - An elevation of privilege vulnerability exists when the Windows Background Intelligent Transfer Service (BITS) IIS module improperly handles uploaded content. An attacker who successfully exploited this vulnerability could upload restricted file types to an IIS-hosted folder. (CVE-2020-1255) - An elevation of privilege vulnerability exists in the way that the Windows Network Connections Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1291) - An elevation of privilege vulnerability exists in Windows Installer because of the way Windows Installer handles certain filesystem operations. (CVE-2020-1302) - An elevation of privilege vulnerability exists when the Windows Backup Service improperly handles file operations. (CVE-2020-1271) - An elevation of privilege vulnerability exists in Windows Text Service Framework (TSF) when the TSF server fails to properly handle messages sent from TSF clients. An attacker who successfully exploited this vulnerability could run arbitrary code in a privileged process. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-1314) - An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation. (CVE-2020-1272) * 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 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 June 2020 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.
