The vulnerability can be triggered via the modino, username, newpwd, or pptpdnetseg parameters, all of which are passed via HTTP POST and used in unsafe sprintf calls without proper length validation. A remote attacker can exploit this flaw through a crafted POST request, which may cause a Denial of Service (DoS). In certain scenarios, this issue could potentially be leveraged to achieve remote code execution.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-787"],"references":["https://github.com/TTTJJJWWW/AHU-IoT-vulnerable/blob/main/Tenda/FH1206/fromPptpUserAdd.md","https://github.com/laohouzju/PoC/blob/main/Tenda%20FH1206%20fromPptpUserAdd_newpwd.md","https://github.com/laohouzju/PoC/blob/main/Tenda%20FH1206%20fromPptpUserAdd_pptpdnetseg.md","https://github.com/laohouzju/PoC/blob/main/Tenda%20FH1206%20fromPptpUserAdd_username.md"],"products":["tenda:fh1206_firmware"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-42987","score":0.01307,"percentile":0.7059,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
