CVE-2025-32455 is a high-severity vulnerability (CVSS 7.7) affecting the ON Semiconductor Quantenna Wi-Fi chipset, specifically through version 8.0.0.28 of its SDK. The vulnerability is classified under CWE-88, which involves improper neutralization of argument delimiters in commands, commonly known as argument injection. The issue arises from a local control script named router_command.sh, which accepts a run_cmd argument that is vulnerable to command injection. This means that an attacker with local access to the device could craft malicious input to execute arbitrary commands on the underlying system without requiring authentication or user interaction. The CVSS vector indicates that the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality and integrity is high, while availability is not affected. The vulnerability remains unpatched at the time of disclosure, although the vendor has issued best practice guidelines for implementors. Since the exploit requires local access, the threat surface is limited to entities with physical or network-level local access to the device hosting the vulnerable chipset. However, given the critical role of Wi-Fi chipsets in network infrastructure, successful exploitation could lead to unauthorized command execution, potentially compromising the device and the network it serves.

For European organizations, this vulnerability poses a significant risk to network security, especially for those deploying devices using the Quantenna Wi-Fi chipset in routers, access points, or IoT gateways. Exploitation could lead to unauthorized access to network infrastructure, data breaches, and manipulation of network traffic. Confidentiality and integrity of sensitive data transmitted over affected devices could be compromised, potentially exposing corporate secrets or personal data protected under GDPR. The lack of availability impact reduces the risk of denial-of-service, but the ability to execute arbitrary commands locally could facilitate lateral movement within internal networks or persistent footholds for attackers. Organizations with distributed networks or remote offices using such hardware may face challenges in detecting and mitigating exploitation due to the local attack vector. Additionally, the absence of a patch means that mitigation relies heavily on configuration and operational controls, increasing the burden on security teams.

1. Immediate network segmentation to isolate devices using the Quantenna Wi-Fi chipset from critical infrastructure and sensitive data environments. 2. Restrict local access to affected devices by enforcing strict physical security and limiting administrative network access to trusted personnel only. 3. Implement network access controls such as 802.1X authentication and MAC address filtering to reduce unauthorized local network access. 4. Monitor logs and network traffic for unusual command execution patterns or anomalies related to router_command.sh or similar scripts. 5. Apply the vendor's best practice guidelines rigorously, including disabling or restricting the use of the vulnerable run_cmd argument where possible. 6. Engage with ON Semiconductor for updates and patches, and plan for timely firmware or SDK upgrades once available. 7. Conduct regular security assessments and penetration tests focusing on local access vectors to identify potential exploitation attempts. 8. Educate network administrators about the risks of local command injection vulnerabilities and the importance of minimizing local attack surfaces.
