Dell BIOS contains an Improper Restriction of Excessive Authentication Attempts vulnerability. A local authenticated malicious administrator could exploit this vulnerability to bypass excessive NVMe password attempt mitigations in order to carry out a brute force attack.

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
Latitude_5310_2-in-1_firmware Dell * 1.7.0 (excluding)

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]
