{"schemaVersion":3,"id":"CVE-2018-10703","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An issue was discovered on Moxa AWK-3121 1.14 devices. It provides functionality so that an administrator can run scripts on the device to troubleshoot any issues. However, the same functionality allows an attacker to execute commands on the device. The POST parameter \"iw_serverip\" is susceptible to buffer overflow. By crafting a packet that contains a string of 480 characters, it is possible for an attacker to execute the attack.","dates":{"published":"2019-06-07T19:56:34.000Z","modified":"2024-08-05T07:46:46.439Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":6.8,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.02605,"percentile":0.85232,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.14000000000000018,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.02465},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.02465,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.02605,"percentile":0.85232}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.02465,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02605,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02605,
