Vulnerability details

A vulnerability in Cisco Intelligent Node (iNode) Software could allow an unauthenticated, remote attacker to hijack the TLS connection between Cisco iNode Manager and associated intelligent nodes and send arbitrary traffic to an affected device. This vulnerability is due to…

more

the presence of hard-coded cryptographic material. An attacker in a man-in-the-middle position between Cisco iNode Manager and associated deployed nodes could exploit this vulnerability by using the static cryptographic key to generate a trusted certificate and impersonate an affected device. A successful exploit could allow the attacker to read data that is meant for a legitimate device, modify the startup configuration of an associated node, and, consequently, cause a denial of service (DoS) condition for downstream devices that are connected to the affected node.

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-321

Supply chain protection includes scrutiny of cryptographic implementations, reducing hard-coded keys planted by untrusted vendors.

addresses: CWE-321

Functional and assurance requirements specified in acquisition can prohibit hard-coded cryptographic keys in delivered products.

addresses: CWE-321

Proper key establishment and management processes directly preclude embedding static cryptographic keys in source code or binaries.

addresses: CWE-321

Approved PKI issuance and trust stores replace ad-hoc or hard-coded keys with properly managed, signed certificates.

addresses: CWE-321

Assessments can uncover and prevent suppliers from shipping components that contain hard-coded cryptographic keys.
