CVE-2025-26378
📋 TL;DR
A missing authorization vulnerability in Q-Free MaxTime allows authenticated low-privileged users to reset passwords, including administrator accounts, via crafted HTTP requests. This affects all installations running version 2.11.0 or earlier. Attackers with basic user access can escalate privileges to administrative control.
💻 Affected Systems
- Q-Free MaxTime
📦 What is this software?
Maxtime by Q Free
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers gain administrative access, modify configurations, access sensitive data, and potentially disrupt operations.
Likely Case
Privilege escalation leading to unauthorized administrative access, data exposure, and potential lateral movement within the network.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring in place to detect unusual password reset activities.
🎯 Exploit Status
Requires authenticated access but only low privileges. Crafting HTTP requests to the vulnerable endpoint is straightforward for attackers with basic web skills.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version > 2.11.0
Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-26378
Restart Required: No
Instructions:
1. Contact Q-Free for the latest patched version. 2. Backup current configuration. 3. Apply the update following vendor instructions. 4. Verify authorization checks are properly implemented.
🔧 Temporary Workarounds
Network Access Control
allRestrict access to MaxTime administration interfaces to trusted IP addresses only.
Use firewall rules to limit access to MaxTime ports (e.g., iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT)
Enhanced Monitoring
allMonitor for unusual password reset activities, especially for administrator accounts.
Configure log alerts for POST requests to password reset endpoints from non-admin users
🧯 If You Can't Patch
- Implement strict network segmentation to isolate MaxTime from other critical systems
- Enforce multi-factor authentication for all user accounts to reduce impact of credential compromise
🔍 How to Verify
Check if Vulnerable:
Check MaxTime version via web interface or configuration files. If version <= 2.11.0, system is vulnerable.Check Version:
Check web interface or configuration files for version information. No single command available for all deployments.Verify Fix Applied:
After patching, test that low-privileged users cannot reset administrator passwords via HTTP requests.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to password reset endpoints from low-privileged users
- Multiple failed login attempts followed by password reset requests
- Administrator password reset events from non-admin IP addresses
Network Indicators:
- HTTP requests to /maxprofile/users/reset-password or similar endpoints with unusual parameters
- Traffic patterns showing privilege escalation attempts
SIEM Query:
source="maxtime_logs" AND (uri_path="/reset-password" OR uri_path="/password/reset") AND user_role!="admin" AND status=200
