Vulnerability Data
A vulnerability in the monitoring application of Cisco Industrial Network Director could allow an authenticated, local attacker to access a static secret key used to store both local data and credentials for accessing remote systems. This vulnerability is due to…
more
a static key value stored in the application used to encrypt application data and remote credentials. An attacker could exploit this vulnerability by gaining local access to the server Cisco Industrial Network Director is installed on. A successful exploit could allow the attacker to decrypt data allowing the attacker to access remote systems monitored by Cisco Industrial Network Director.

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.
Supplier evaluation and secure acquisition practices make it harder for hard-coded credentials to be introduced via procured products.
Requiring security functional requirements and acceptance criteria allows contracts to prohibit hard-coded credentials in delivered systems or components.
Supplier risk reviews identify and discourage hard-coded credentials in delivered products or services.
Enables users to notice when hard-coded credentials have been exploited for unauthorized access.
Security training explicitly warns against hard-coded credentials, lowering their use in systems.
Policy and procedures prohibit hard-coded credentials in favor of managed authentication.
External identity providers eliminate the need for hard-coded credentials in applications.
Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.AA-01's credential/key-management processes can reduce the incentive to embed secrets but do not address or detect hard-coded values in source code, so the weakness remains fully possible.
Data-at-rest protection policies require proper key management and therefore discourage hard-coded keys.
Data-in-transit protection similarly depends on non-hard-coded keys for encryption.
Configuration baselines and reviews can prohibit hard-coded keys in deployed artifacts.
Secure-SDLC activities such as code review and secret scanning directly prevent embedding static keys.
PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.

Education on secure configuration practices discourages technical staff from embedding or relying on hard-coded credentials in systems and applications.
