BlackVue DR750-2CH LTE v.1.012_2022.10.26 was discovered to contain a weak default passphrase which can be easily cracked via a brute force attack if the WPA2 handshake is intercepted.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Dr750-2ch_lte_firmware Blackvue 1.012_2022.10.26 (including) 1.012_2022.10.26 (including)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
