Published: Sun Jun 08 2025 (06/08/2025, 21:04:12 UTC)
Source: CVE Database V5
Vendor/Project: ON Semiconductor
Product: Quantenna Wi-Fi chipset

Description

The Quantenna Wi-Fi chipset ships with a local control script, router_command.sh (in the get_syslog_from_qtn argument), that is vulnerable to command injection. This is an instance of CWE-88, "Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')," and is estimated as a CVSS 7.7 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). This issue affects Quantenna Wi-Fi chipset through version 8.0.0.28 of the latest SDK, and appears to be unpatched at the time of this CVE record's first publishing, though the vendor has released a best practices guide for implementors of this chipset.

Technical Analysis

CVE-2025-32458 is a high-severity vulnerability 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 in a local control script named router_command.sh, particularly in the get_syslog_from_qtn argument. This script fails to properly sanitize input, allowing an attacker with local access to inject arbitrary commands. The CVSS 3.1 score of 7.7 reflects a high impact on confidentiality and integrity, with no impact on availability. The vector indicates that exploitation requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N). The scope is unchanged (S:U), but the vulnerability can lead to complete compromise of confidentiality and integrity of the device's data. Although no public exploits have been reported yet and no patches are available at the time of publication, the vendor has issued best practice guidelines for implementors. This vulnerability is critical because it allows an unauthenticated local attacker to execute arbitrary commands on the device, potentially leading to unauthorized data access or manipulation. The lack of required privileges or user interaction lowers the barrier for exploitation in environments where local access is possible, such as through compromised internal networks or physical access to devices. The affected component, the Quantenna Wi-Fi chipset, is embedded in various wireless routers and access points, making this a significant risk for network infrastructure relying on these chipsets.

Potential Impact

For European organizations, this vulnerability poses a significant risk to network security infrastructure that incorporates the Quantenna Wi-Fi chipset. Successful exploitation could lead to unauthorized command execution on network devices, compromising the confidentiality and integrity of sensitive data transmitted or stored on these devices. This could facilitate lateral movement within corporate networks, data exfiltration, or manipulation of network configurations, potentially disrupting business operations or violating data protection regulations such as GDPR. Since the vulnerability requires local access, it is particularly concerning in environments with less controlled physical or network access, such as branch offices, public-facing Wi-Fi networks, or shared workspaces. The high confidentiality and integrity impact could lead to exposure of sensitive corporate or customer data, undermining trust and incurring regulatory penalties. Additionally, the absence of a patch increases the window of exposure, emphasizing the need for immediate mitigations. The threat is amplified in sectors with critical infrastructure or sensitive data, including finance, healthcare, and government agencies within Europe.

Mitigation Recommendations

Given the absence of an official patch, European organizations should implement several targeted mitigations: 1) Restrict local access to devices using the Quantenna chipset by enforcing strict network segmentation and access controls, limiting access to trusted personnel and systems only. 2) Monitor and audit local command execution logs on affected devices to detect anomalous or unauthorized command invocations, focusing on the router_command.sh script usage. 3) Apply vendor-recommended best practices for secure implementation of the chipset, including disabling or restricting the vulnerable script where feasible. 4) Employ network intrusion detection systems (NIDS) to identify suspicious lateral movement or command injection attempts within internal networks. 5) Where possible, replace or upgrade hardware to versions or alternatives not affected by this vulnerability. 6) Educate IT and security teams about the vulnerability to ensure rapid response to any signs of exploitation. 7) Implement strict physical security controls to prevent unauthorized physical access to network devices. These measures collectively reduce the risk of exploitation until an official patch or firmware update is released.
