Official description

Dell Client Platform BIOS contains a Use of Default Cryptographic Key Vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Secure Boot bypass and arbitrary code execution.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Use of Default Credentials

The product uses default credentials (such as passwords or cryptographic keys) for potentially critical functionality.

How developers prevent this class of flaw

  • Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
  • Force the administrator to change the credential upon installation.
  • The product administrator could change the defaults upon installation or during operation.
