<< Back VID 26776 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description The Hotfix (MS16-084, 3169991) for 'Cumulative Security Update for Internet Explorer' has not been applied. This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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 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. Multiple Microsoft Internet Explorer Memory Corruption Vulnerabilities Remote code execution vulnerabilities exist when Internet Explorer improperly accesses objects in memory. 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, the attacker 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. Internet Explorer Security Feature Bypass Vulnerability A restricted ports security feature bypass vulnerability exists for Internet Explorer. An attacker could take advantage of the vulnerability to trick a user into connecting to a remote system. Multiple Scripting Engine Memory Corruption Vulnerabilities Multiple remote code execution vulnerabilities exist in the way that the Jscript 9 and VBScript engines render when handling objects in memory in Internet Explorer. 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. Multiple Internet Explorer Information Disclosure Vulnerabilities Information disclosure vulnerabilities exist when the Microsoft Browser improperly handles objects in memory. An attacker who successfully exploited the vulnerabilities could obtain information to further compromise the user¡¯s system.

An attacker who successfully exploited the vulnerabilities could obtain information to further compromise the user¡¯s system. Microsoft Browser Spoofing Vulnerability A spoofing vulnerability exists when a Microsoft browser does not properly parse HTTP content. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. Microsoft Browser Spoofing Vulnerability A spoofing vulnerability exists when the Microsoft Browser in reader mode does not properly parse HTML content. An attacker who successfully exploited this vulnerability could trick a user by redirecting them to a specially crafted website. The specially crafted website could spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services.
