{"schemaVersion":3,"id":"CVE-2019-1054","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A security feature bypass vulnerability exists in Edge that allows for bypassing Mark of the Web Tagging (MOTW). Failing to set the MOTW means that a large number of Microsoft security technologies are bypassed.\nIn a web-based attack scenario, an attacker could host a malicious website that is designed to exploit the security feature bypass. Alternatively, in an email or instant message attack scenario, the attacker could send the targeted user a specially crafted .url file that is designed to exploit the bypass. Additionally, compromised websites or websites that accept or host user-provided content could contain specially crafted content to exploit the security feature bypass. However, in all cases an attacker would have no way to force a user to view attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could entice a user to either click a link that directs the user to the attacker's site or send a malicious attachment.\nThe security update addresses the security feature bypass by correcting how Edge handles MOTW tagging.","dates":{"published":"2019-06-12T13:49:41.000Z","modified":"2025-05-20T17:49:50.237Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.1,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:H/Au:N/C:P/I:P/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":5,"severity":"medium","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":5.1,"severity":"medium","vector":"AV:N/AC:H/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01604,"percentile":0.75515,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.01604},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.01604,"percentile":0.75515}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01629,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01604,"percentile":null},{"date":"2026-10-05T00:00:00
