{"schemaVersion":3,"id":"CVE-2018-16588","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Privilege escalation can occur in the SUSE useradd.c code in useradd, as distributed in the SUSE shadow package through 4.2.1-27.9.1 for SUSE Linux Enterprise 12 (SLE-12) and through 4.5-5.39 for SUSE Linux Enterprise 15 (SLE-15). Non-existing intermediate directories are created with mode 0777 during user creation. Given that they are world-writable, local attackers might use this for privilege escalation and other unspecified attacks.  NOTE: this would affect non-SUSE users who took useradd.c code from a 2014-04-02 upstream pull request; however, no non-SUSE distribution is known to be affected.","dates":{"published":"2018-09-26T22:00:00.000Z","modified":"2024-08-05T10:24:32.999Z","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":0.00301,"percentile":0.21418,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00301},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00324,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00301,"percentile":0.21418}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00324,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00301,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00301,"percentile":nul
