The device runs a CGI binary (index.cgi) to offer a management web application. Once authenticated with valid credentials in this web portal, a potential attacker could submit any \"Address\" value and it would be copied to a second variable with a \"strcpy\" vulnerable function without checking its length. Because of this, it is possible to send a long address value to overflow the process stack, controlling the function return address.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-121"],"references":["https://www.cisa.gov/uscert/ics/advisories/icsa-22-137-01","https://www.cisa.gov/uscert/ics/advisories/icsa-22-137-01"],"products":["circutor:compact_dc-s_basic_firmware"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-1669","score":0.00808,"percentile":0.56881,"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).
