The attacker would then have to convince the user to open the specially crafted attachment. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.\nPlease see the Security Updates table for the link to the updated app. Alternatively you can download and install the Installer using the links provided in the FAQ section.\nPlease see the Mitigations and Workaround sections for important information about steps you can take to protect your system from this vulnerability.\nDecember 27 2023 Update:\nIn recent months, Microsoft Threat Intelligence has seen an increase in activity from threat actors leveraging social engineering and phishing techniques to target Windows OS users and utilizing the ms-appinstaller URI scheme.\nTo address this increase in activity, we have updated the App Installer to disable the ms-appinstaller protocol by default and recommend other potential mitigations.\n" } ], "metrics": [ { "cvssV3_1": { "baseScore": 7.1, "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C", "version": "3.1" }, "format": "CVSS", "scenarios": [ { "lang": "en-US", "value": "GENERAL" } ] } ], "problemTypes": [ { "descriptions": [ { "description": "Spoofing", "lang": "en-US", "type": "Impact" } ] } ], "providerMetadata": { "dateUpdated": "2024-05-29T14:44:37.753Z", "orgId": "f38d906d-7342-40ea-92c1-6c4a2c6478c8", "shortName": "microsoft" }, "references": [ { "tags": [ "x_refsource_MISC" ], "url": "https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2021-43890" }, { "url": "https://www.bleepingcomputer.com/news/microsoft/microsoft-disables-msix-protocol-handler-abused-in-malware-attacks/" }, { "url": "https://thehackernews.com/2023/12/microsoft-disables-msix-app-installer.html" }, { "url": "https://www.microsoft.com/en-us/security/blog/2023/12/28/financially-motivated-threat-actors-misusing-app-installer/" }, { "url": "https://github.com/ChrisTitusTech/winutil/pull/26" } ], "title": "Windows AppX Installer Spoofing Vulnerability" } }, "cveMetadata": { "assignerOrgId": "f38d906d-7342-40ea-92c1-6c4a2c6478c8", "assignerShortName": "microsoft", "cveId": "CVE-2021-43890", "datePublished": "2021-12-15T14:15:35", "dateReserved": "2021-11-16T00:00:00", "dateUpdated": "2024-08-04T04:10:17.079Z", "state": "PUBLISHED" }, "dataType": "CVE_RECORD", "dataVersion": "5.1" }
