Both programs parse the contents of /proc/net/arp using sscanf() with \"%s\" format specifiers into fixed-size stack buffers without length validation. Specifically, one function writes user-controlled data into a single-byte buffer, and the other into adjacent small arrays without bounds checking. An attacker who controls the contents of /proc/net/arp can trigger memory corruption, leading to denial of service or potential arbitrary code execution."}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","baseScore":5.1,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":2.5,"impactScore":2.5}]},"weaknesses":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-121"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:totolink:a720r_firmware:4.1.5cu.614_b20230630:*:*:*:*:*:*:*","matchCriteriaId":"BCA249C9-68D4-48FE-B0CA-77ECF53DDE3B"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:totolink:a720r:-:*:*:*:*:*:*:*","matchCriteriaId":"A1DE5168-B787-462C-B024-2B8F73759034"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:totolink:lr1200gb_firmware:9.1.0u.6619_b20230130:*:*:*:*:*:*:*","matchCriteriaId":"00F36DE9-D043-4C8B-9EF9-8DA669589E85"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:totolink:lr1200gb:-:*:*:*:*:*:*:*","matchCriteriaId":"8442849E-5B06-41A1-8DA8-827FBD7A34E5"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:totolink:nr1800x_firmware:9.1.0u.6681_b20230703:*:*:*:*:*:*:*","matchCriteriaId":"7F9DCAA5-1EC6-44A1-9606-B6FBF29DEC65"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:totolink:nr1800x:-:*:*:*:*:*:*:*","matchCriteriaId":"B4D2D0E8-2678-4238-8229-83450ECA1153"}]}]}],"references":[{"url":"http://totolink.com","source":"cve@mitre.org","tags":["Broken Link"]},{"url":"https://github.com/yifan20020708/SGTaint-0-day/blob/main/ToToLink/ToToLink-A720R/CVE-2025-60686.md","source":"cve@mitre.org","tags":["Exploit","Third Party Advisory"]},{"url":"https://www.totolink.net/","source":"cve@mitre.org","tags":["Product"]}]}}]}
