CVE-2025-3460
📋 TL;DR
The Quantenna Wi-Fi chipset's set_tx_pow script is vulnerable to command injection, allowing local attackers to execute arbitrary commands with elevated privileges. This affects devices using Quantenna Wi-Fi chipsets through SDK version 8.0.0.28. The vulnerability requires local access but no authentication.
💻 Affected Systems
- Quantenna Wi-Fi chipsets
- Devices using Quantenna Wi-Fi technology
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via arbitrary command execution with root privileges, potentially leading to persistent backdoors, data theft, or device takeover.
Likely Case
Local privilege escalation allowing attackers to gain root access on affected devices, modify system configurations, or install malware.
If Mitigated
Limited impact if proper access controls restrict local user access and command execution is properly sanitized.
🎯 Exploit Status
Exploitation requires local access but no authentication. The vulnerability is straightforward to exploit once local access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://community.onsemi.com/s/article/QCS-Quantenna-Wi-Fi-product-support-and-security-best-practices
Restart Required: Yes
Instructions:
No official patch available. Follow vendor best practices guide for implementors. Monitor vendor for firmware updates.
🔧 Temporary Workarounds
Remove or restrict set_tx_pow script
linuxRemove the vulnerable script or restrict its permissions to prevent execution
chmod 000 /path/to/set_tx_pow
rm /path/to/set_tx_pow
Implement input validation
linuxModify the script to properly sanitize and validate input parameters
🧯 If You Can't Patch
- Restrict local access to devices using network segmentation and access controls
- Implement strict privilege separation and limit user permissions on affected devices
🔍 How to Verify
Check if Vulnerable:
Check if set_tx_pow script exists on the system and examine its version/source code for input validationCheck Version:
Check firmware/SDK version through vendor-specific commands or device management interfaceVerify Fix Applied:
Verify the script has been removed, permissions restricted, or input validation has been implemented📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns
- Unexpected privilege escalation attempts
- set_tx_pow script execution with suspicious parameters
