{"schemaVersion":3,"id":"CVE-2018-12238","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Norton prior to 22.15; Symantec Endpoint Protection (SEP) prior to 12.1.7454.7000 & 14.2; Symantec Endpoint Protection Small Business Edition (SEP SBE) prior to NIS-22.15.1.8 & SEP-12.1.7454.7000; and Symantec Endpoint Protection Cloud (SEP Cloud) prior to 22.15.1 may be susceptible to an AV bypass issue, which is a type of exploit that works to circumvent one of the virus detection engines to avoid a specific type of virus protection. One of the antivirus engines depends on a signature pattern from a database to identify malicious files and viruses; the antivirus bypass exploit looks to alter the file being scanned so it is not detected.","dates":{"published":"2018-11-29T14:00:00.000Z","modified":"2024-08-05T08:30:58.948Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":7.8,"severity":"high","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.6,"severity":"medium","vector":"AV:L/AC:L/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00402,"percentile":0.33006,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00402},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00423,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00402,"percentile":0.33006}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00423,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00402,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00402,"percentile":nul
