The vulnerability allows for unauthenticated kinetic effects and information disclosure on the faucets. It is possible to use the Bluetooth Low Energy (BLE) connectivity to read and write to many BLE characteristics on the device. Some of these control the flow of water, the sensitivity of the sensors, and information about maintenance.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-306"],"references":["https://www.tenable.com/security/research/tra-2021-26-0","https://www.tenable.com/security/research/tra-2021-26-0"],"products":["sloan:basys_efx-100_firmware","sloan:basys_efx-150_firmware","sloan:basys_efx-175_firmware","sloan:basys_efx-177_firmware","sloan:basys_efx-180_firmware","sloan:basys_efx-200_firmware","sloan:basys_efx-250_firmware","sloan:basys_efx-275_firmware","sloan:basys_efx-277_firmware","sloan:basys_efx-280_firmware","sloan:basys_efx-300_firmware","sloan:basys_efx-350_firmware","sloan:basys_efx-375_firmware","sloan:basys_efx-377_firmware","sloan:basys_efx-380_firmware","sloan:basys_efx-600_firmware","sloan:basys_efx-650_firmware","sloan:basys_efx-675_firmware","sloan:basys_efx-677_firmware","sloan:basys_efx-680_firmware","sloan:basys_efx-800_firmware","sloan:basys_efx-850_firmware","sloan:optima_eaf-100_firmware","sloan:optima_eaf-150_firmware","sloan:optima_eaf-200_firmware","sloan:optima_eaf-225_firmware","sloan:optima_eaf-250_firmware","sloan:optima_eaf-275_firmware","sloan:optima_eaf-350_firmware","sloan:optima_eaf-700_firmware","sloan:optima_eaf-750_firmware","sloan:optima_ebf-187_firmware","sloan:optima_ebf-415_firmware","sloan:optima_ebf-425_firmware","sloan:optima_ebf-550_firmware","sloan:optima_ebf-615_firmware","sloan:optima_ebf-650_firmware","sloan:optima_ebf-665_firmware","sloan:optima_ebf-750_firmware","sloan:optima_ebf-775_firmware","sloan:optima_ebf-850_firmware","sloan:optima_ebf-85_firmware","sloan:optima_etf-410_firmware","sloan:optima_etf-420_firmware","sloan:optima_etf-500_firmware","sloan:optima_etf-600_firmware","sloan:optima_etf-610_firmware","sloan:optima_etf-660_firmware","sloan:optima_etf-700_firmware","sloan:optima_etf-770_firmware"],"source":"nvd","synced_at":"2026-10-19T21:20:07.141963181+00:00"},"epss":{"cve":"CVE-2021-20107","score":0.00543,"percentile":0.45636,"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).
