{"schemaVersion":3,"id":"CVE-2020-12038","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Products that use EDS Subsystem: Version 28.0.1 and prior (FactoryTalk Linx software (Previously called RSLinx Enterprise): Versions 6.00, 6.10, and 6.11, RSLinx Classic: Version 4.11.00 and prior, RSNetWorx software: Version 28.00.00 and prior, Studio 5000 Logix Designer software: Version 32 and prior) is vulnerable. A memory corruption vulnerability exists in the algorithm that matches square brackets in the EDS subsystem. This may allow an attacker to craft specialized EDS files to crash the EDSParser COM object, leading to denial-of-service conditions.","dates":{"published":"2020-05-19T21:36:54.000Z","modified":"2024-08-04T11:48:58.157Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.5,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.3,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.02562,"percentile":0.84968,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.06300000000000021,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.02499},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.02562,"percentile":0.84968}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02499,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02562,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":
