CVE-2025-46117
📋 TL;DR
This vulnerability allows authenticated attackers to execute arbitrary commands as root on Ruckus wireless controllers by exploiting improper input sanitization in a hidden debug script. Affected systems include CommScope Ruckus Unleashed and ZoneDirector products. Attackers need authenticated access to the restricted CLI to trigger the vulnerability.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root-level command execution, allowing attackers to install persistent backdoors, steal sensitive data, pivot to other network segments, or render the controller inoperable.
Likely Case
Privilege escalation from authenticated user to root, enabling attackers to modify network configurations, intercept wireless traffic, or disrupt wireless services.
If Mitigated
Limited impact if proper network segmentation, access controls, and monitoring prevent attackers from reaching the vulnerable interface.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once access is obtained. The vulnerability details and exploitation methods are publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Ruckus Unleashed 200.15.6.212.14, 200.17.7.0.139 or later; ZoneDirector 10.5.1.0.279 or later
Vendor Advisory: https://support.ruckuswireless.com/security_bulletins/330
Restart Required: Yes
Instructions:
1. Download the latest firmware from Ruckus support portal. 2. Backup current configuration. 3. Apply firmware update through web interface or CLI. 4. Reboot the controller. 5. Verify the update was successful.
🔧 Temporary Workarounds
Restrict CLI Access
allLimit access to the restricted CLI interface to only trusted administrators using network access controls and strong authentication.
Network Segmentation
allIsolate wireless controllers in a dedicated management VLAN with strict firewall rules preventing unauthorized access.
🧯 If You Can't Patch
- Implement strict access controls to limit who can authenticate to the controller's CLI interface
- Monitor for unusual CLI activity and command execution patterns
🔍 How to Verify
Check if Vulnerable:
Check the controller firmware version via web interface (System > About) or CLI (show version). Compare against affected versions.Check Version:
show versionVerify Fix Applied:
Confirm firmware version is equal to or higher than the patched versions listed in the fix section.📡 Detection & Monitoring
Log Indicators:
- Unusual CLI access patterns
- Execution of .ap_debug.sh script
- Commands executed with root privileges from non-admin accounts
Network Indicators:
