CVE-2025-32459
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Quantenna Wi-Fi chipset ships with a local control script, router_command.sh (in the sync_time 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 summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA command injection vulnerability exists in the Quantenna Wi-Fi chipset's local control script router_command.sh, specifically in the sync_time argument. The script improperly handles input, allowing an attacker with local access to inject arbitrary commands due to insufficient sanitization of arguments passed to system calls (CWE-88). This requires no privileges or user interaction to exploit.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Quantenna Wi-Fi chipset presenceSearch for Quantenna-related files, modules, or firmware identifiers on the system. Common paths may include /etc/quantenna, /lib/firmware/quantenna, or check kernel modules for quantenna drivers (e.g., lsmod | grep quantenna).Affected if The system uses any Quantenna Wi-Fi chipset hardware or firmware.
-
Locate the router_command.sh scriptSearch for the vulnerable script using: find / -name 'router_command.sh' 2>/dev/null. Common locations may include /usr/local/bin, /bin, /sbin, or proprietary firmware directories.Affected if The script router_command.sh exists on the system.
-
Verify sync_time argument handlingExamine the script contents for the sync_time parameter. Use grep or cat to view the script and identify how the sync_time argument is processed (look for system(), exec(), or shell command calls involving this argument).Affected if The script contains a sync_time argument that passes input directly to shell commands without sanitization.
-
Confirm firmware/product versionCheck the device firmware version or product name against the affected list: Qcs Ax3 S5, Qcs Ax2 A12, Qcs Ax2 T12, Qcs Ax2 T8, Qd840, Qhs710, Qsr10ga, Qsr10gu. Use commands like cat /proc/version, cat /etc/firmware_version, or vendor-specific tools.Affected if The firmware version matches any of the listed Onsemi Quantenna products.
A system is affected if it runs any version of the listed Onsemi Quantenna firmware and contains the router_command.sh script with an accessible sync_time argument that is not sanitized before use in shell commands.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedSince the vendor has not released a patch, implementors should apply input validation to any data passed to the sync_time argument, follow the vendor's best practices guide for secure implementation, and consider restricting local access to the affected script until an official firmware update is available.
- There is no vendor-provided patch or firmware update for this vulnerability as of the CVE publication date.
- The vendor (Quantenna) has only released a best practices guide for implementors, which is not a security patch.
- Contact your device manufacturer (the company that uses the Quantenna chipset) to request firmware updates and inquire about remediation timelines.
- If you are a device manufacturer implementing this chipset, refer to the Quantenna best practices guide for mitigation guidance on the router_command.sh script.
- Consider network segmentation to limit local attack surface, as this is a local command injection (AV:L).
