{"cve":"CVE-2017-17436","nvd":{"published":"2017-12-07T00:29:00.287","modified":"2026-06-17T01:10:48.023","status":"Modified","description":"An issue was discovered in the software on Vaultek Gun Safe VT20i products. There is no encryption of the session between the Android application and the safe. The website and marketing materials advertise that this communication channel is encrypted with \"Highest Level Bluetooth Encryption\" and \"Data transmissions are secure via AES256 bit encryption.\" These claims, however, are not true. Moreover, AES256 bit encryption is not supported in the Bluetooth Low Energy (BLE) standard, so it would have to be at the application level. This lack of encryption allows an individual to learn the passcode by eavesdropping on the communications between the application and the safe.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-326"],"references":["https://vaulteksafe.com/index.php/cve-2017-17435/","https://www.twosixlabs.com/bluesteal-popping-gatt-safes/","https://vaulteksafe.com/index.php/cve-2017-17435/","https://www.twosixlabs.com/bluesteal-popping-gatt-safes/"],"products":["vaulteksafe:vt20i_firmware"],"source":"nvd","synced_at":"2026-10-19T20:47:56.471723566+00:00"},"epss":{"cve":"CVE-2017-17436","score":0.00202,"percentile":0.10124,"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).
