{"schemaVersion":3,"id":"CVE-2018-2439","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The SAP Internet Graphics Server (IGS), 7.20, 7.20EXT, 7.45, 7.49, 7.53, has insufficient request validation (for example, where the request is validated for authenticity and validity) and under certain conditions, will process invalid requests. Several areas of the SAP Internet Graphics Server (IGS) did not require sufficient input validation. Namely, the SAP Internet Graphics Server (IGS) HTTP and RFC listener, SAP Internet Graphics Server (IGS) portwatcher when registering a portwatcher to the multiplexer and the SAP Internet Graphics Server (IGS) multiplexer had insufficient input validation and thus allowing a malformed data packet to cause a crash.","dates":{"published":"2018-07-10T18:00:00.000Z","modified":"2024-08-05T04:21:33.655Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.9,"severity":"medium","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":5.9,"severity":"medium","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/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":0.01536,"percentile":0.74624,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.10800000000000011,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.01428},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01428,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.01536,"percentile":0.74624}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.01428,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01536,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.015
