CVE-2024-31406

8.8 HIGH

📋 TL;DR

Active debug code vulnerability in RoamWiFi R10 devices allows network-adjacent unauthenticated attackers to perform unauthorized operations. This affects RoamWiFi R10 devices running firmware versions prior to 4.8.45. Attackers on the same network can exploit leftover debugging functionality to compromise device security.

💻 Affected Systems

Products:
  • RoamWiFi R10
Versions: All versions prior to 4.8.45
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: All default configurations are vulnerable. No special configuration required for exploitation.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device takeover allowing attacker to reconfigure device, intercept network traffic, install malware, or use device as pivot point for further network attacks.

🟠

Likely Case

Unauthorized configuration changes, network disruption, credential theft, or installation of backdoors on vulnerable devices.

🟢

If Mitigated

Limited impact if devices are isolated from untrusted networks and have strong network segmentation.

🌐 Internet-Facing: MEDIUM - Devices directly exposed to internet are vulnerable, but exploit requires network adjacency which internet exposure provides.
🏢 Internal Only: HIGH - Internal network devices are vulnerable to any compromised or malicious internal host on same network segment.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires network access but no authentication. Debug code likely provides direct access to privileged functions.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 4.8.45

Vendor Advisory: https://www.roamwifi.hk/product.jsp

Restart Required: Yes

Instructions:

1. Log into RoamWiFi R10 web interface. 2. Navigate to System > Firmware Upgrade. 3. Download firmware version 4.8.45 from vendor site. 4. Upload and apply firmware update. 5. Device will automatically restart after update.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate RoamWiFi R10 devices on separate VLAN or network segment to limit attack surface.

Access Control Lists

all

Implement network ACLs to restrict access to RoamWiFi R10 devices to authorized management hosts only.

🧯 If You Can't Patch

  • Physically isolate RoamWiFi R10 devices from untrusted networks and users
  • Implement strict network monitoring and alerting for unauthorized access attempts to these devices

🔍 How to Verify

Check if Vulnerable:

Check firmware version in web interface under System > Status. If version is below 4.8.45, device is vulnerable.

Check Version:

No CLI command available. Use web interface at http://[device-ip] and navigate to System > Status.

Verify Fix Applied:

After update, verify firmware version shows 4.8.45 in System > Status page.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts to debug endpoints
  • Unexpected configuration changes
  • Unusual network traffic from device

Network Indicators:

  • Traffic to debug ports or endpoints from unauthorized sources
  • Unexpected outbound connections from device

SIEM Query:

source_ip=[roamwifi-device] AND (http_user_agent CONTAINS "debug" OR uri_path CONTAINS "debug")
