Detailsinfo

A vulnerability, which was classified as critical, has been found in Vaultek Gun Safe VT20i (version unknown). Affected by this issue is an unknown function. The manipulation with an unknown input leads to a inadequate encryption vulnerability. Using CWE to declare the problem leads to CWE-326. The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The bug was discovered 10/06/2017. The weakness was released 12/07/2017 (Website). The advisory is available at vaulteksafe.com. This vulnerability is handled as CVE-2017-17436 since 12/05/2017.
