CVE-2024-56448
Huawei Harmonyos 2.0.0 … 4.2.0
Raw vector
CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-56448 is a medium-severity Code Injection (CWE-94) vulnerability in Huawei Harmonyos. Its CVSS base score is 6.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 12th 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-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-56448 is a vulnerability involving improper access control in the home screen widget module of Huawei consumer devices. This flaw, published on January 8, 2025, is classified under CWE-94 (Code Injection) and NVD-CWE-Other, with a CVSS v3.1 base score of 6.7 (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). Successful exploitation may primarily affect system availability, though the high-impact vector also enables significant confidentiality and integrity compromises.
Exploitation requires local access to the device and high privileges (PR:H), with low attack complexity and no user interaction needed. A privileged local attacker could leverage this improper access control in the home screen widget module to execute arbitrary code or manipulate system resources, potentially leading to high confidentiality loss (e.g., data exposure), integrity violations (e.g., data tampering), and availability disruption (e.g., denial of service).
Huawei's security bulletin at https://consumer.huawei.com/en/support/bulletin/2025/1/ provides details on affected devices and recommends applying the available patches or updates to mitigate the vulnerability. Security practitioners should verify device firmware versions against the advisory and enforce privilege restrictions to limit exposure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

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's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
