The /goform/formMultiApnSetting handler uses sprintf() to copy the user-supplied pincode parameter into a fixed 132-byte stack buffer with no bounds checks. This allows an attacker to corrupt adjacent stack memory, crash the web server, and (under certain conditions) may enable arbitrary 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:H/I:H/A:H","score":9.8},"cwes":["CWE-121"],"references":["https://drive.proton.me/urls/HJCJYAC7JM#XtHcm3P7QaYk","https://github.com/actuator/cve/blob/main/Kuwfi/CVE-2025-68706.txt","https://github.com/actuator/cve/tree/main/Kuwfi","https://kuwfi.com/products/kuwfi-gigabit-wireless-router-4g-lte-wifi-router-dual-band-portable-wifi-modem-hotspot-64-user-with-gigabit-wan-lan-rj11-port"],"products":["kuwfi:ac900_firmware"],"source":"nvd","synced_at":"2026-10-19T22:18:08.089039631+00:00"},"epss":{"cve":"CVE-2025-68706","score":0.04971,"percentile":0.92135,"date":"2026-10-25"},"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).
