CVE-2024-4428
📋 TL;DR
This CVE describes a critical authentication and authorization bypass vulnerability in Menulux Information Technologies Management Portal that allows unauthenticated attackers to access sensitive functions and collect user data. All systems running Management Portal through version 21.05.2024 are affected. The vulnerability enables attackers to compromise the management interface without valid credentials.
💻 Affected Systems
- Menulux Information Technologies Management Portal
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the management portal allowing attackers to exfiltrate all user data, modify system configurations, deploy backdoors, and potentially pivot to other systems in the network.
Likely Case
Unauthenticated attackers accessing sensitive user information, modifying portal settings, and potentially gaining administrative privileges over the management system.
If Mitigated
Limited impact if network segmentation prevents external access and strong authentication controls are in place for internal users.
🎯 Exploit Status
The CWE-306 classification indicates missing authentication for critical functions, suggesting exploitation requires minimal technical skill once the vulnerable endpoint is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.usom.gov.tr/bildirim/tr-24-1356
Restart Required: No
Instructions:
1. Contact Menulux Information Technologies for patch availability. 2. Check the USOM advisory for updates. 3. Apply any available patches immediately. 4. Verify the fix by testing authentication requirements.
🔧 Temporary Workarounds
Network Access Restriction
linuxRestrict access to the management portal to trusted IP addresses only
iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [PORT] -j DROP
Web Application Firewall Rules
allImplement WAF rules to block unauthenticated access to management endpoints
🧯 If You Can't Patch
- Isolate the management portal on a separate VLAN with strict access controls
- Implement multi-factor authentication at the network level before reaching the portal
🔍 How to Verify
Check if Vulnerable:
Attempt to access management portal functions without authentication. If you can perform administrative actions or access sensitive data without credentials, the system is vulnerable.Check Version:
Check the portal interface footer or about page for version information. The exact command varies by deployment.Verify Fix Applied:
Test that all management portal functions require valid authentication and proper authorization checks. Verify unauthorized access attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Failed authentication attempts followed by successful access to protected endpoints
- Access to /admin or /management paths without auth logs
- Unusual user agent strings accessing sensitive endpoints
Network Indicators:
- HTTP requests to management endpoints without authentication headers
- Traffic to sensitive URLs from unexpected source IPs
SIEM Query:
source="web_logs" AND (url="*/admin*" OR url="*/manage*" OR url="*/config*") AND NOT (status="401" OR status="403")
