CVE-2025-32458
📋 TL;DR
This vulnerability allows local attackers to execute arbitrary commands on systems using Quantenna Wi-Fi chipsets by exploiting command injection in the router_command.sh script. It affects devices running Quantenna SDK versions through 8.0.0.28. The vulnerability requires local access but no authentication, making it accessible to any user on the system.
💻 Affected Systems
- Quantenna Wi-Fi chipsets
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root privileges, allowing installation of persistent backdoors, data exfiltration, and lateral movement within the network.
Likely Case
Local privilege escalation leading to unauthorized access to sensitive system files, network configuration changes, and potential pivot to other systems.
If Mitigated
Limited impact if proper access controls restrict local user accounts and command execution is monitored.
🎯 Exploit Status
Command injection vulnerabilities typically have low exploitation complexity, especially when unauthenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://community.onsemi.com/s/article/QCS-Quantenna-Wi-Fi-product-support-and-security-best-practices
Restart Required: No
Instructions:
No official patch available. Follow vendor's best practices guide and implement workarounds.
🔧 Temporary Workarounds
Remove or restrict router_command.sh script
linuxRemove the vulnerable script or restrict its execution permissions to prevent exploitation
chmod 000 /path/to/router_command.sh
rm /path/to/router_command.sh
Implement input validation
linuxModify the script to properly validate and sanitize user input before execution
Edit router_command.sh to validate all arguments and escape special characters
🧯 If You Can't Patch
- Restrict local user access to systems using vulnerable chipsets
- Implement strict monitoring of command execution and system logs for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if router_command.sh exists and examine its get_syslog_from_qtn argument handling for proper input validationCheck Version:
Check Quantenna SDK version through vendor-specific commands or configuration filesVerify Fix Applied:
Verify script has been removed, permissions restricted, or input validation implemented📡 Detection & Monitoring
Log Indicators:
- Unusual command execution patterns
- Multiple failed command attempts
- Suspicious arguments passed to router_command.sh
Network Indicators:
- Unexpected outbound connections from affected devices
- Unusual network configuration changes
SIEM Query:
Process execution logs containing 'router_command.sh' with unusual arguments or from unexpected users
