CVE-2025-32457 is a high-severity vulnerability affecting the ON Semiconductor Quantenna Wi-Fi chipset, specifically in a local control script named router_command.sh used within the get_file_from_qtn argument. This vulnerability is classified under CWE-88, which involves improper neutralization of argument delimiters in commands, commonly referred to as argument injection. The flaw allows an attacker with local access to the device to inject arbitrary commands into the script execution flow. Because the vulnerability can be exploited without any authentication or user interaction, and with low attack complexity, it poses a significant risk to the confidentiality and integrity of affected systems. The CVSS 3.1 score of 7.7 reflects these factors, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is high on confidentiality and integrity, as arbitrary commands could be executed, potentially leading to data leakage or unauthorized system modifications. Availability is not directly impacted. The vulnerability affects versions of the Quantenna Wi-Fi chipset SDK up to 8.0.0.28, and as of the initial publication date, no patch has been released, though the vendor has provided a best practices guide for implementors. This suggests that mitigation currently relies on secure configuration and limiting local access. The Quantenna chipset is embedded in various Wi-Fi routers and access points, meaning that devices using this chipset could be compromised if an attacker gains local access, such as through physical access or via other local network exploits that escalate privileges. The lack of known exploits in the wild reduces immediate risk but does not diminish the potential severity if exploited.

For European organizations, this vulnerability presents a significant risk primarily in environments where devices using the Quantenna Wi-Fi chipset are deployed, such as enterprise wireless infrastructure or critical network edge devices. Successful exploitation could allow attackers to execute arbitrary commands locally, potentially leading to unauthorized access to sensitive data, manipulation of network traffic, or pivoting within internal networks. Confidentiality breaches could expose personal data protected under GDPR, leading to regulatory penalties and reputational damage. Integrity compromises could disrupt network operations or facilitate further attacks. Although the attack vector is local, many European organizations have complex network environments where local access might be obtained through compromised internal hosts or insufficiently segmented networks. The absence of a patch means organizations must rely on configuration and access controls to mitigate risk. The impact is heightened in sectors with stringent security requirements, such as finance, healthcare, and government, where Wi-Fi infrastructure is critical and must be secured against lateral movement and privilege escalation.

1. Restrict local access to devices using the Quantenna Wi-Fi chipset by enforcing strict physical security controls and network segmentation to limit exposure to trusted personnel and systems only. 2. Implement robust network access controls, including NAC (Network Access Control) solutions, to prevent unauthorized devices or users from gaining local network access where the chipset is deployed. 3. Monitor and audit device logs for unusual command execution or access patterns that could indicate exploitation attempts. 4. Follow the vendor's best practices guide meticulously, which may include disabling or restricting the use of vulnerable scripts like router_command.sh or limiting the parameters passed to such scripts. 5. Maintain up-to-date inventories of all network devices to identify those using the affected chipset and prioritize them for enhanced monitoring and protection. 6. Prepare for patch deployment by establishing communication channels with ON Semiconductor for updates and testing patches in controlled environments before production rollout. 7. Employ endpoint protection and intrusion detection systems capable of detecting anomalous command execution or privilege escalation attempts on devices hosting the vulnerable chipset.
