{"schemaVersion":3,"id":"CVE-2022-44731","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified in SIMATIC WinCC OA V3.15 (All versions < V3.15 P038), SIMATIC WinCC OA V3.16 (All versions < V3.16 P035), SIMATIC WinCC OA V3.17 (All versions < V3.17 P024), SIMATIC WinCC OA V3.18 (All versions < V3.18 P014). The affected component allows to inject custom arguments to the Ultralight Client backend application under certain circumstances.\n\nThis could allow an authenticated remote attacker to inject arbitrary parameters when starting the client via the web interface (e.g., open attacker chosen panels with the attacker's credentials or start a Ctrl script).","dates":{"published":"2022-12-13T00:00:00.000Z","modified":"2025-04-21T13:43:45.574Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.4,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:P/RL:O/RC:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:P/RL:O/RC:C","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00567,"percentile":0.45998,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.03499999999999996,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00532},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00567,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00567,"percentile":0.45998}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00532,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00547,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00547,"percentile
