CVE-2025-26341
📋 TL;DR
This vulnerability allows unauthenticated remote attackers to reset arbitrary user passwords in Q-Free MaxTime systems via crafted HTTP requests. It affects all installations running version 2.11.0 or earlier. Attackers can gain unauthorized access to user accounts without any authentication.
💻 Affected Systems
- Q-Free MaxTime
📦 What is this software?
Maxtime by Q Free
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise where attackers reset all user passwords, take over administrative accounts, and gain full control over the MaxTime system and connected infrastructure.
Likely Case
Attackers reset passwords for multiple user accounts, gaining unauthorized access to sensitive data, manipulating time/attendance records, and potentially escalating privileges.
If Mitigated
Limited impact with proper network segmentation and authentication controls, but still exposes the vulnerable endpoint to internal threats.
🎯 Exploit Status
The vulnerability requires only crafted HTTP requests to the vulnerable endpoint, making exploitation straightforward for attackers with network access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version > 2.11.0
Vendor Advisory: https://www.nozominetworks.com/labs/vulnerability-advisories-cve-2025-26341
Restart Required: Yes
Instructions:
1. Contact Q-Free for updated version >2.11.0. 2. Backup current configuration. 3. Apply the patch/upgrade. 4. Restart MaxTime services. 5. Verify functionality.
🔧 Temporary Workarounds
Network Access Control
linuxRestrict network access to MaxTime web interface to trusted IPs only
iptables -A INPUT -p tcp --dport [MaxTime_port] -s [trusted_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [MaxTime_port] -j DROP
Web Server Authentication
allImplement basic authentication at web server level for the vulnerable endpoint
# Add to Apache .htaccess: AuthType Basic
# AuthName "Restricted Area"
# AuthUserFile /path/to/.htpasswd
# Require valid-user
🧯 If You Can't Patch
- Implement strict network segmentation to isolate MaxTime from untrusted networks
- Deploy a WAF with rules to block unauthorized password reset requests
🔍 How to Verify
Check if Vulnerable:
Check if MaxTime version is ≤2.11.0 and test if unauthenticated password reset requests to /maxprofile/accounts/ routes succeedCheck Version:
Check MaxTime web interface admin panel or configuration files for version informationVerify Fix Applied:
Verify version is >2.11.0 and test that unauthenticated password reset requests now fail with proper authentication errors📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful password reset
- Password reset requests from unusual IP addresses
- POST requests to /maxprofile/accounts/reset without authentication
Network Indicators:
- Unusual HTTP traffic patterns to password reset endpoints
- Multiple password reset requests from single source in short time
SIEM Query:
source="MaxTime" AND (uri_path="/maxprofile/accounts/reset" OR uri_path="/maxprofile/accounts/*") AND http_method="POST" AND NOT auth_success="true"
