Vulnerability Data

Autel MaxiCharger AC Elite Business C50 BLE Hardcoded Credentials Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Autel MaxiCharger AC Elite Business C50 charging stations. Authentication is not required to exploit this vulnerability.…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

IA-5 Authenticator Management good match

Authenticator management requires secure distribution and handling of credentials, structurally discouraging hard-coded values.

SC-12 Cryptographic Key Establishment and Management good match

Cryptographic key management mandates proper establishment and handling instead of embedding keys in code.

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 partial match
blocks

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.

PR.AA-02 none match
blocks

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.

PR.DS-01 none match
blocks

PR.DS-01 addresses encryption and integrity of stored data but never touches credential or key management practices, so it neither prevents hard-coded credentials nor removes any of their risk.
