CVE-2017-17435
An issue was discovered in the software on Vaultek Gun Safe VT20i products, aka BlueSteal. An attacker can remotely unlock any safe in this product line without a valid PIN code. Even though the phone application requires it and there is a field to supply the PIN code in an authorization request, the safe does not check the PIN code, so an attacker can obtain authorization using any value. Once an attacker sees the Bluetooth Low Energy (BLE) advertisement for the safe, they need only to write a BLE characteristic to enable notifications, and send a crafted getAuthor packet that returns a temporary key, and an unlock packet including that temporary key. The safe then opens after the unlock packet is processed, with no verification of PIN or other credentials.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Base score: 8.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.58%
- Percentile among all scored CVEs: 46
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

"value": "Se ha descubierto una vulnerabilidad en el software en productos Vaultek Gun Safe VT20i, también conocidos como BlueSteal. Un atacante podría desbloquear de manera remota cualquier caja fuerte en esta línea de productos sin necesidad de un código PIN válido. Incluso aunque la aplicación lo requiera y haya un campo que reemplace el código PIN de seguridad en una petición de autorización, la caja fuerte no verifica el código PIN, por lo que un atacante puede obtener autorización utilizando cualquier valor. Una vez que el atacante observa el anuncio del Bluetooth de baja energía (Bluetooth LE) para la caja fuerte, solo necesita sobrescribir una característica Bluetooth LE para habilitar las notificaciones, enviar un paquete getAuthor manipulado que devuelva una clave temporal y desbloquear el paquete que incluye esa clave temporal. Entonces, la caja fuerte se abre cuando se procesa el paquete de desbloqueo sin verificación de PIN u otro tipo de credenciales."
