CVE-2025-26361

9.1 CRITICAL

📋 TL;DR

CVE-2025-26361 allows unauthenticated remote attackers to factory reset Q-Free MaxTime devices via crafted HTTP requests due to missing authentication on critical functions. This affects all Q-Free MaxTime versions up to and including 2.11.0. Organizations using these traffic management systems are vulnerable to service disruption.

💻 Affected Systems

Products:
  • Q-Free MaxTime
Versions: ≤ 2.11.0
Operating Systems: Not specified, likely embedded Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Affects the maxprofile/setup/routes.lua component. All deployments with vulnerable versions are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system disruption with loss of all configuration, traffic data, and operational settings requiring manual reconfiguration and causing extended traffic management outages.

🟠

Likely Case

Service disruption requiring device reconfiguration and temporary loss of traffic management capabilities.

🟢

If Mitigated

Minimal impact if devices are behind firewalls with strict network controls and authentication requirements.

🌐 Internet-Facing: HIGH - Directly exploitable via HTTP requests without authentication.
🏢 Internal Only: HIGH - Even internally, any network access to the device allows exploitation without credentials.

🎯 Exploit Status

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

Simple HTTP request exploitation requiring no authentication or special privileges.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: > 2.11.0

Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-26361

Restart Required: Yes

Instructions:

1. Contact Q-Free for patched version >2.11.0. 2. Backup device configuration. 3. Apply update following vendor instructions. 4. Restart device. 5. Verify functionality.

🔧 Temporary Workarounds

Network Segmentation

linux

Isolate MaxTime devices behind firewalls with strict inbound rules.

iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP

Web Application Firewall

all

Deploy WAF to block malicious HTTP requests to setup endpoints.

🧯 If You Can't Patch

  • Implement strict network access controls allowing only authorized management IPs.
  • Monitor for HTTP requests to /maxprofile/setup/ endpoints and alert on suspicious activity.

🔍 How to Verify

Check if Vulnerable:

Check device version via web interface or CLI. If version ≤2.11.0, device is vulnerable.

Check Version:

Check web interface or consult device documentation for version command.

Verify Fix Applied:

Verify version >2.11.0 and test that unauthenticated HTTP POST requests to setup endpoints return authentication errors.

📡 Detection & Monitoring

Log Indicators:

  • HTTP POST requests to /maxprofile/setup/* endpoints from unauthenticated sources
  • Factory reset events in system logs

Network Indicators:

  • HTTP traffic to device on ports 80/443 with POST requests containing reset parameters

SIEM Query:

source="maxprofile" AND (uri_path="/maxprofile/setup/*" OR event="factory_reset")
