Likely Mitigating Controls AI

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.

addresses: CWE-1392

Mandates replacement of default credentials during secure configuration and provisioning procedures.

addresses: CWE-1392

Policy requires changing or avoiding default credentials during system setup and operation.

addresses: CWE-1392

Unique identification requirement prevents use of default or shared credentials by organizational users.

addresses: CWE-1392

Changing default authenticators prior to first use prevents use of default credentials.

addresses: CWE-1392

Standards-compliant authentication mechanisms typically prohibit default credentials for cryptographic modules.

addresses: CWE-1392

Consistent implementation of the strategy drives removal or mitigation of default credentials in procured systems and services.

addresses: CWE-1392

Security functional requirements and acceptance criteria can stipulate that acquired systems must not use default credentials.

addresses: CWE-1392

Documentation of known configuration vulnerabilities and secure setup practices reduces reliance on default credentials.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.

PR.AA-01 mostly match
prevents

Credential management processes directly require replacing or disabling default passwords and keys.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
