Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Mandates replacement of default credentials during secure configuration and provisioning procedures.
Policy requires changing or avoiding default credentials during system setup and operation.
Unique identification requirement prevents use of default or shared credentials by organizational users.
Changing default authenticators prior to first use prevents use of default credentials.
Standards-compliant authentication mechanisms typically prohibit default credentials for cryptographic modules.
Consistent implementation of the strategy drives removal or mitigation of default credentials in procured systems and services.
Security functional requirements and acceptance criteria can stipulate that acquired systems must not use default credentials.
Documentation of known configuration vulnerabilities and secure setup practices reduces reliance on default credentials.
