Published: 08 June 2025
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, ranked in the top 22.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
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.
