<< Back VID 26796 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description The Hotfix (MS16-119, 3192890) for 'Cumulative Security Update for Microsoft Edge' has not been applied. This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users with administrative user rights. Microsoft Edge Memory Corruption Vulnerability ? CVE-2016-3331 A remote code execution vulnerability exists in the way that Microsoft Edge handles objects in memory. The vulnerability could corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user. Multiple Scripting Engine Memory Corruption Vulnerabilities Multiple remote code execution vulnerabilities exist in the way that the Chakra JavaScript engine renders when handling objects in memory in Microsoft Edge. The vulnerabilities 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 vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerabilities 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. Microsoft Browser Information Disclosure Vulnerability CVE-2016-3267 An information disclosure vulnerability exists when Microsoft Edge does not properly handle objects in memory. The vulnerability could allow an attacker to detect specific files on the user's computer. In a web-based attack scenario, an attacker could host a website that is used to attempt to exploit the vulnerability. Microsoft Browser Information Disclosure Vulnerability CVE-2016-3391 An information disclosure vulnerability exists when Microsoft browsers leave credential data in memory. An attacker who successfully exploited this vulnerability could harvest credentials from a memory dump of the browser process. An attacker would need access to a memory dump from the affected system. Scripting Engine Remote Code Execution Vulnerability CVE-2016-7189 A remote code execution vulnerability exists when Microsoft Edge improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user¡¯s system. Multiple Microsoft Browser Elevation of Privilege Vulnerabilities Elevation of privilege vulnerabilities exist when Microsoft Edge fails to properly secure private namespace. An attacker who successfully exploited these vulnerabilities could gain elevated permissions on the namespace directory of a vulnerable system and gain elevated privileges. Microsoft Browser Security Feature Bypass Vulnerability ? CVE-2016-3392 A security feature bypass vulnerability exists when the Edge Content Security Policy fails to properly handle validation of certain specially crafted documents. * 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://technet.microsoft.com/en-us/library/security/ms16-119 * Platforms Affected: Windows 10 Recommendation Apply the appropriate patch(3192890) for your system, as listed in Microsoft Security Bulletin MS16-119 at https://technet.microsoft.com/en-us/library/security/ms16-119 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com.
