Summary

CVE-2025-28146 is a critical-severity Code Injection (CWE-94) vulnerability in Edimax Br-6478Ac V3 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability CVE-2025-28146 is a command injection flaw, tracked as CWE-94, in the Edimax AC1200 Wave 2 Dual-Band Gigabit Router BR-6478AC V3 running firmware 1.0.15. It resides in the handling of the fota_url parameter passed to the /boafrm/formLtefotaUpgradeQuectel endpoint and received a CVSS 3.1 score of 9.8.

Remote attackers with no credentials or user interaction required can supply crafted input to the endpoint and execute arbitrary operating-system commands on the device. Successful exploitation yields complete control over the router, enabling full read, write, and disruption of device functions and any attached networks.

Public references consist of a technical gist and GitHub repository that reproduce the flaw; neither source nor the CVE record itself documents vendor patches, firmware updates, or recommended mitigations. The associated EPSS score has reached 0.3888 at its observed peak.

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.

PR.PS-06 mostly match
prevents

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 none match
prevents

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.

prevents

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.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
