Attackers can exploit this issue to execute arbitrary code in the context of the currently logged-in user. Failed attacks will cause denial of service conditions. Internet Explorer 9, 10 and 11 are vulnerable.\n\n### Technologies Affected\n\n * Microsoft Internet Explorer 10 \n * Microsoft Internet Explorer 11 \n * Microsoft Internet Explorer 9 \n\n### Recommendations\n\n**Run all software as a nonprivileged user with minimal access rights.** \nTo reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.\n\n**Deploy network intrusion detection systems to monitor network traffic for malicious activity.** \nDeploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits\n\n**Do not follow links provided by unknown or untrusted sources.** \nWeb users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.\n\n**Implement multiple redundant layers of security.** \nMemory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.\n\nUpdates are available. Please see the references or vendor advisory for more information.\n", "published": "2018-09-11T00:00:00", "modified": "2018-09-11T00:00:00", "cvss": {"score": 0.0, "vector": "NONE"}, "href": "https://www.symantec.com/content/symantec/english/en/security-center/vulnerabilities/writeup.html/105257", "reporter": "Symantec Security Response", "references": ["http://www.microsoft.com/ie"], "cvelist": ["CVE-2018-8447"], "lastseen": "2018-09-12T00:45:40", "viewCount": 2, "enchantments": {"score": {"value": 8.4, "vector": "NONE", "modified": "2018-09-12T00:45:40", "rev": 2}, "dependencies": {"references": [{"type": "cve", "idList": ["CVE-2018-8447"]}, {"type": "zdi", "idList": ["ZDI-18-1048"]}, {"type": "openvas", "idList": ["OPENVAS:1361412562310814013", "OPENVAS:1361412562310814014", "OPENVAS:1361412562310814012", "OPENVAS:1361412562310814011", "OPENVAS:1361412562310814215", "OPENVAS:1361412562310814001", "OPENVAS:1361412562310814003", "OPENVAS:1361412562310814015"]}, {"type": "nessus", "idList": ["SMB_NT_MS18_SEP_4457129.NASL", "SMB_NT_MS18_SEP_INTERNET_EXPLORER.NASL", "SMB_NT_MS18_SEP_4457142.NASL", "SMB_NT_MS18_SEP_4457131.NASL", "SMB_NT_MS18_SEP_4457138.NASL", "SMB_NT_MS18_SEP_4457135.NASL", "SMB_NT_MS18_SEP_4457132.NASL", "SMB_NT_MS18_SEP_4458010.NASL", "SMB_NT_MS18_SEP_4457128.NASL", "SMB_NT_MS18_SEP_4457144.NASL"]}, {"type": "kaspersky", "idList": ["KLA11890", "KLA11318"]}, {"type": "talosblog", "idList": ["TALOSBLOG:116422E24074F675755331EBA739BEB9"]}], "modified": "2018-09-12T00:45:40", "rev": 2}, "vulnersScore": 8.4}, "affectedSoftware": [{"name": "Microsoft Internet Explorer", "operator": "eq", "version": "11 "}, {"name": "Microsoft Internet Explorer", "operator": "eq", "version": "9 "}, {"name": "Microsoft Internet Explorer", "operator": "eq", "version": "10 "}]}

(CVE-2018-8470)\n\n - A spoofing vulnerability exists when Microsoft Edge\n improperly handles specific HTML content. An attacker\n who successfully exploited this vulnerability could\n trick a user into believing that the user was on a\n legitimate website. The specially crafted website could\n either spoof content or serve as a pivot to chain an\n attack with other vulnerabilities in web services.\n (CVE-2018-8425)\");\n # https://support.microsoft.com/en-us/help/4457128/windows-10-update-kb4457128\n script_set_attribute(attribute:\"see_also\", value:\"http://www.nessus.org/u?dee71c23\");\n script_set_attribute(attribute:\"solution\", value:\n\"Apply Cumulative Update KB4457128.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C\");\n script_set_cvss_temporal_vector(\"CVSS2#E:H/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:H/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2018-8421\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"Exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"true\");\n script_set_attribute(attribute:\"exploit_framework_core\", value:\"true\");\n script_set_attribute(attribute:\"exploited_by_malware\", value:\"true\");\n script_set_attribute(attribute:\"metasploit_name\", value:'Microsoft Windows ALPC Task Scheduler Local Privilege Elevation');\n script_set_attribute(attribute:\"exploit_framework_metasploit\", value:\"true\");\n script_set_attribute(attribute:\"exploit_framework_canvas\", value:\"true\");\n script_set_attribute(attribute:\"canvas_package\", value:'CANVAS');\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2018/09/11\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2018/09/11\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2018/09/11\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:microsoft:windows\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/a:microsoft:edge\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Windows : Microsoft Bulletins\");\n\n script_copyright(english:\"This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"smb_check_rollup.nasl\", \"smb_hotfixes.nasl\", \"ms_bulletin_checks_possible.nasl\");\n script_require_keys(\"SMB/MS_Bulletin_Checks/Possible\");\n script_require_ports(139, 445, \"Host/patch_management_checks\");\n\n exit(0);\n}\n\ninclude(\"audit.inc\");\ninclude(\"smb_hotfixes_fcheck.inc\");\ninclude(\"smb_hotfixes.inc\");\ninclude(\"smb_func.inc\");\ninclude(\"misc_func.inc\");\n\nget_kb_item_or_exit(\"SMB/MS_Bulletin_Checks/Possible\");\n\nbulletin = \"MS18-09\";\nkbs = make_list('4457128');\n\nif (get_kb_item(\"Host/patch_management_checks\")) hotfix_check_3rd_party(bulletin:bulletin, kbs:kbs, severity:SECURITY_HOLE);\n\nget_kb_item_or_exit(\"SMB/Registry/Enumerated\");\nget_kb_item_or_exit(\"SMB/WindowsVersion\", exit_code:1);\n\nif (hotfix_check_sp_range(win10:'0') <= 0) audit(AUDIT_OS_SP_NOT_VULN);\n\nshare = hotfix_get_systemdrive(as_share:TRUE, exit_on_fail:TRUE);\nif (!is_accessible_share(share:share)) audit(AUDIT_SHARE_FAIL, share);\n\nif (\n smb_check_rollup(os:\"10\",\n sp:0,\n os_build:\"17134\",\n rollup_date:\"09_2018\",\n bulletin:bulletin,\n rollup_kb_list:[4457128])\n)\n{\n replace_kb_item(name:'SMB/Missing/'+bulletin, value:TRUE);\n hotfix_security_hole();\n hotfix_check_fversion_end();\n exit(0);\n}\nelse\n{\n hotfix_check_fversion_end();\n audit(AUDIT_HOST_NOT, hotfix_get_audit_report());\n}\n", "cvss": {"score": 10.0, "vector": "AV:N/AC:L/Au:N/C:C/I:C/A:C"}}], "openvas": [{"lastseen": "2020-06-08T23:06:10", "bulletinFamily": "scanner", "cvelist": ["CVE-2018-8447", "CVE-2018-8452", "CVE-2018-8457", "CVE-2018-8315", "CVE-2018-8470"], "description": "This host is missing a critical security\n update according to Microsoft security updates KB4457426.", "modified": "2020-06-04T00:00:00", "published": "2018-09-12T00:00:00", "id": "OPENVAS:1361412562310814001", "href": "http://plugins.openvas.org/nasl.php?oid=1361412562310814001", "type": "openvas", "title": "Microsoft Internet Explorer Multiple Vulnerabilities (KB4457426)", "sourceData": "###############################################################################\n# OpenVAS Vulnerability Test\n#\n# Microsoft Internet Explorer Multiple Vulnerabilities (KB4457426)\n#\n# Authors:\n# Rinu Kuriakose <krinu@secpod.com>\n#\n# Copyright:\n# Copyright (C) 2018 Greenbone Networks GmbH, http://www.greenbone.net\n#\n# This program is free software; you can redistribute it and/or modify\n# it under the terms of the GNU General Public License version 2\n# (or any later version), as published by the Free Software Foundation.\n#\n# This program is distributed in the hope that it will be useful,\n# but WITHOUT ANY WARRANTY; without even the implied warranty of\n# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

set of security updates today for a variety of its products that address a variety of bugs. The latest Patch Tuesday covers 61 vulnerabilities, 17 of which are rated \"critical,\" 43 that are rated \"important\" and one that is considered to have \"moderate\" severity. \n \nThe advisories cover bugs in the Internet Explorer web browser, Jet Database Engine and the Chakra scripting engine, among other products and software. \n \nThis update also includes two critical advisories, one of which covers security updates to Adobe Flash, and another that deals with a denial-of-service vulnerability in the Microsoft Windows operating system. \n \n \n \n\n\n## Critical vulnerabilities\n\n \nMicrosoft released coverage for 17 critical bugs. Cisco Talos believes 16 of these are of special importance and need to be addressed by users immediately. \n \n[CVE-2018-0965](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-0965>) is a remote code execution vulnerability in the Windows Hyper-V hypervisor. An attacker can exploit this vulnerability by running a specially crafted application on a guest system that would cause the system operating Hyper-V to execute arbitrary code. The flaw lies in the way that Hyper-V validates inputs from an authenticated user on a guest OS. \n \n[CVE-2018-8367](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8367>) is a remote code execution vulnerability in the Chakra scripting engine. The engine improperly handles objects in memory in the Microsoft Edge web browser that could allow an attacker to corrupt the system's memory and execute arbitrary code with the user's credentials. \n \n[CVE-2018-8420](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8420>) is a remote code execution vulnerability in Microsoft XML Core Services MSXML. An attacker could trick the user into visiting a specially crafted, malicious website designed to invoke MSXML through a web browser, allowing the attacker to eventually run code and take control of the user's system. \n \n[CVE-2018-8461](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8461>) is a remote code execution vulnerability in Internet Explorer that exists when the web browser improperly accesses objects in memory. This bug could corrupt memory in a way that an attacker could execute arbitrary code with the same rights as the current user. A user would need to visit a specially crafted, malicious website to trigger this vulnerability. \n \n[CVE-2018-8475](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8475>) is a remote code execution vulnerability in Windows OS, which exists due to the image-loading functionality improperly handling malformed image files. An attacker could exploit this bug by convincing a user to load a malformed image file from either a web page, email or other method. \n \n[CVE-2018-8332](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8332>) is a remote code execution vulnerability in the Windows font library. There are multiple ways in which an attacker could exploit this flaw, including convincing the user to click on a malicious web page or providing the user with a specially crafted, malicious document. \n \n[CVE-2018-8391](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8391>) is a remote code execution vulnerability in the Chakra scripting engine. An attacker can exploit this flaw if a user is logged on with an administrative account. \n \n[CVE-2018-8439](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8439>) is a remote code execution vulnerability in the Windows Hyper-V hypervisor. The bug exists in Hyper-V's validation on a host server. An attacker can exploit this flaw by running a specially crafted application on a guest operating system that could lead to the machine running Hyper-V executing arbitrary code. \n \n[CVE-2018-8447](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8447>) is a remote code execution vulnerability in Internet Explorer. An attacker could exploit this vulnerability by tricking a user into visiting a specially crafted web page while using the Internet Explorer browser, or by taking advantage of a compromised website through advertisements or attachments that the user would have to click on. \n \n[CVE-2018-8456](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8456>) and [CVE-2018-](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8459>)[8459](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8459>) are remote code execution vulnerabilities that exist in the Chakra scripting engine's handling of objects in memory. This bug could corrupt memory in a way that an attacker could execute arbitrary code with the same rights as the current user. \n \n[CVE-2018-8457](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8457>) is a remote code execution vulnerability that exists in the way Microsoft web browsers' scripting engines handle objects in memory. An attacker could host a specially crafted website to exploit this vulnerability, and then convince the user to visit the website while using a Microsoft web browser, or they could embed an ActiveX control that is marked \"safe for initialization\" in a Microsoft Office file or an application that hosts the browser's rendering engine. \n \n[CVE-2018-8464](<https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8464>) is a remote code execution vulnerability in Microsoft Edge's PDF reader that exists in the way the reader handles objects in memory.
