CVE-2025-32458 in Quantenna Wi-Fi Chipset
Summary
by MITRE • 06/09/2025
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.

The vulnerability CVE-2025-32458 resides within the Quantenna Wi-Fi chipset ecosystem, specifically targeting a local control script named router_command.sh that processes input through the get_syslog_from_qtn argument. This represents a critical security flaw that allows attackers to inject malicious commands into the system's execution pipeline. The vulnerability manifests as an improper neutralization of argument delimiters in a command, which directly maps to CWE-88, a well-documented weakness in software systems where command line arguments are not properly sanitized before being passed to system execution functions. The CVSS score of 7.7 indicates a high-severity issue that can be exploited with local access, requiring no user interaction and potentially leading to significant confidentiality and integrity impacts.
The technical implementation of this vulnerability stems from the insecure handling of command line arguments within the router_command.sh script, which likely concatenates user-provided input directly into system commands without adequate validation or sanitization. Attackers can exploit this weakness by crafting malicious input that contains command delimiters such as semicolons, pipes, or ampersands, which would then be interpreted by the shell as separate commands rather than simple arguments. This creates a pathway for arbitrary command execution on the device, potentially allowing threat actors to escalate privileges, extract sensitive information, or modify system configurations. The vulnerability affects all versions of the Quantenna Wi-Fi chipset up to version 8.0.0.28 of the SDK, indicating a widespread exposure across multiple firmware implementations that have not received a patch update.
The operational impact of this vulnerability extends beyond simple command injection, as it represents a fundamental security flaw in the chipset's design that could enable attackers to gain unauthorized access to network infrastructure devices. The fact that this vulnerability affects the local control script suggests that even legitimate users with access to the device could potentially exploit it to execute unauthorized commands, creating both insider threat risks and external attack vectors. The unpatched nature of this issue at the time of CVE publication indicates that device administrators may be operating with vulnerable firmware that lacks proper input validation mechanisms, leaving network infrastructure exposed to potential compromise. This vulnerability also aligns with ATT&CK technique T1059.001, which covers command and scripting interpreter execution, and T1068, which involves exploit for privilege escalation.
Organizations utilizing Quantenna Wi-Fi chipsets should immediately implement mitigations including disabling unnecessary local access to the router_command.sh script, implementing strict input validation for all user-supplied arguments, and applying the vendor's best practices guide for secure implementation. Network segmentation and monitoring should be enhanced to detect anomalous command execution patterns that may indicate exploitation attempts. The vulnerability demonstrates the importance of proper input sanitization and the potential consequences of inadequate security controls in embedded systems. Given the CVSS score and the nature of the attack vector, administrators should prioritize this vulnerability in their risk assessment and remediation schedules, as the potential for unauthorized access to network infrastructure devices poses significant operational and security risks to enterprise networks.
