Summary

CVE-2025-7020 is a medium-severity Reliance on Security Through Obscurity (CWE-656) vulnerability in Asrg (inferred from references). Its CVSS base score is 5.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique System Information Discovery (T1082); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-8 (Security and Privacy Engineering Principles) and SC-13 (Cryptographic Protection) — see the control section below for these in your framework.

Vulnerability Data

An incorrect encryption implementation vulnerability exists in the system log dump feature of BYD's DiLink 3.0 OS (e.g. in the model ATTO3). An attacker with physical access to the vehicle can bypass the encryption of log dumps on the In-Vehicle…

Infotainment (IVI) unit's storage. This allows the attacker to access and read system logs containing sensitive data, including personally identifiable information (PII) and location data. This vulnerability was introduced in a patch intended to fix CVE-2024-54728.

V6.3.4

Mitigating Controls (NIST 800-53 r5) AI

SC-13 Cryptographic Protection good match

Requires selection and implementation of approved cryptographic methods whose strength does not rest on secrecy of design.

SA-8 Security and Privacy Engineering Principles good match

Security and privacy engineering principles explicitly prohibit reliance on obscurity and require documented, verifiable protection mechanisms.

SC-28 Protection of Information at Rest good match

Requires cryptographic or equivalent protection of information at rest, eliminating dependence on obscurity for confidentiality.

SC-8 Transmission Confidentiality and Integrity good match

Mandates actual cryptographic or equivalent protection of transmitted data rather than depending on hidden algorithms or keys.

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.PS-06 mostly match

prevents

Secure SDLC practices explicitly reject obscurity-based designs in favor of proven controls.

GV.PO-01 partial match

prevents

Risk-management policy can mandate avoidance of obscurity but does not itself implement technical alternatives.

ID.RA-05 partial match

prevents

Risk analysis surfaces obscurity as a weakness yet does not prevent its introduction.

A.8.24 Use of cryptography mostly match

prevents

Mandates use of cryptography whose strength is independent of secrecy of design or keys.

A.8.27 Secure system architecture and engineering principles mostly match

prevents

Requires secure architecture and engineering principles that reject reliance on obscurity.

A.8.5 Secure authentication mostly match

prevents

Requires authentication mechanisms whose strength does not depend on secrecy of implementation.

A.8.28 Secure coding partial match

prevents

Secure-coding rules prohibit hidden or undocumented security mechanisms.
