Summary
<p>A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user.</p> <p>To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Word software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.</p> <p>The security update addresses the vulnerability by correcting how Microsoft Word handles files in memory.</p>

In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.\u003c/p\u003e\\n\u003cp\u003eThe security update addresses the vulnerability by correcting how Microsoft Word handles files in memory.\u003c/p\u003e\\n\"},{\"lang\":\"es\",\"value\":\"Se presenta una vulnerabilidad de ejecuci\u00f3n de c\u00f3digo remota en el software Microsoft Word cuando presenta un fallo al manejar apropiadamente objetos en memoria, tambi\u00e9n se conoce como \\\"Microsoft Word Remote Code Execution Vulnerability\\\".\u0026#xa0;Este ID de CVE es diferente de CVE-2020-1218\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"secure@microsoft.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9},{\"source\":\"nvd@nist.gov\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"baseScore\":8.8,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.8,\"impactScore\":5.9}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:N/C:P/I:P/A:P\",\"baseScore\":6.8,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"NONE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"PARTIAL\",\"availabilityImpact\":\"PARTIAL\"},\"baseSeverity\":\"MEDIUM\",\"exploitabilityScore\":8.6,\"impactScore\":6.4,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":true}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:365_apps:-:*:*:*:enterprise:*:*:*\",\"matchCriteriaId\":\"40C15EDD-98D4-4D06-BA06-21AE0F33C72D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:office:2016:*:*:*:*:macos:*:*\",\"matchCriteriaId\":\"8B615D7A-B7F2-44DF-8699-EB8367ADE65C\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:office:2019:*:*:*:*:-:*:*\",\"matchCriteriaId\":\"C5282C83-86B8-442D-851D-B54E88E8B1F1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:office:2019:*:*:*:*:macos:*:*\",\"matchCriteriaId\":\"40961B9E-80B6-42E0-A876-58B3CE056E4E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:office_online_server:-:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"E98AE986-FA31-4301-8025-E8915BA4AC5E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:microsoft:sharepoint_server:2019:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"6122D014-5BF1-4AF4-8B4D-80205ED7785E\"}]}]}],\"references\":[{\"url\":\"https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1338\",\"source\":\"secure@microsoft.com\",\"tags\":[\"Patch\",\"Vendor Advisory\"]},{\"url\":\"https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1338\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\",\"Vendor Advisory\"]}]}}"
