Because the Bluetooth LE support is implemented without a requirement for pairing or security, any attacker can access the GATT server of the device and can sniff the data being broadcasted while a measurement is being done. Also, saved data can also be extracted over a Bluetooth connection. In addition, an attacker can launch a man-in-the-middle attack against data integrity.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":[],"references":["https://payatu.com/advisory/lack-of-bluetooth-le-encryption-and-access-control-in-dr-trust-ecg-or-ekg-pen","https://payatu.com/advisory/lack-of-bluetooth-le-encryption-and-access-control-in-dr-trust-ecg-or-ekg-pen"],"products":["drtrust:electrocardiogram_pen_firmware"],"source":"nvd","synced_at":"2026-10-19T21:09:20.498348299+00:00"},"epss":{"cve":"CVE-2020-15486","score":0.00508,"percentile":0.43386,"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).
