Summary

CVE-2025-3460 is a high-severity Argument Injection (CWE-88) vulnerability in Onsemi Qcs-Ax3-S5 Firmware. Its CVSS base score is 7.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 41% 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 Quantenna Wi-Fi chipset contains a local control script named set_tx_pow that is vulnerable to command injection due to improper neutralization of argument delimiters. This issue, tracked as CVE-2025-3460 and classified under CWE-88, affects the chipset through version 8.0.0.28 of the latest SDK and carries a CVSS 7.7 score reflecting local attack vector, low complexity, and no required privileges or user interaction.

An attacker with the ability to invoke the script locally can inject arbitrary arguments, resulting in high impact to confidentiality and integrity on the affected device while availability remains unaffected. The vulnerability exists in the chipset firmware itself and can be reached without network access or elevated permissions.

Vendor guidance published by onsemi recommends that implementors follow a set of security best practices for the Quantenna chipset, though the CVE record indicates the underlying issue remained unpatched at the time of disclosure. The associated EPSS score has remained low, with a current value of 0.0098 and a peak of 0.0109.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing can discover argument-injection flaws in command-construction code but does not stop their introduction.

Input validation directly stops construction of command strings containing unneutralized delimiters or injected arguments.

finds

Security testing can detect argument injection but does not prevent it at the source.

prevents

Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.

prevents

Application security requirements include explicit rules for safe command-line argument handling and escaping.

prevents

Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.

prevents

Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.

none

Change management can catch unsafe command patterns during reviews but is not a direct mitigation.
