{"schemaVersion":3,"id":"CVE-2025-60684","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (sub_42F32C function). The web interface reads the \"lang\" parameter and constructs Help URL strings using sprintf() into fixed-size stack buffers without proper length validation. Maliciously crafted input can overflow these buffers, potentially leading to arbitrary code execution or memory corruption, without requiring authentication.","dates":{"published":"2025-11-13T00:00:00.000Z","modified":"2026-07-05T01:19:18.493Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00549,"percentile":0.45104,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.03300000000000004,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00516},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00549,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00549,"percentile":0.45104}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00516,"percentile":null},{"date":"2026
