Vulnerability Data

A firmware update mechanism in the affected charging controller fails to validate the authenticity of firmware packages delivered through the device's management interface. Because cryptographic signatures are not verified, an attacker with the ability to interfere with or impersonate the…

Mitigating Controls (NIST 800-53 r5) AI

CM-14 Signed Components good match

Requires digital signature verification before component installation, directly stopping execution of code downloaded without integrity checks.

SI-7 Software, Firmware, and Information Integrity good match

Employs integrity verification tools that can identify missing or failed checks on downloaded software after the fact.

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.

ID.RA-09 full match
prevents

Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.

PR.DS-02 mostly match
prevents

Requires cryptographic integrity protections (signatures/hashes) for data-in-transit, covering downloaded code.

PR.PS-05 mostly match
prevents

Prevents execution of unauthorized software, blocking the outcome of an unchecked download.

A.5.21 Managing information security in the ICT supply chain partial match
prevents

Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.

A.8.8 Management of technical vulnerabilities none match
none

Requiring suppliers to disclose vulnerabilities and mandating verified updates lowers the chance that code lacking integrity checks will be deployed.
