CVE-2024-5404

9.8 CRITICAL

📋 TL;DR

CVE-2024-5404 allows unauthenticated remote attackers to change the admin password on moneo appliances due to a weak password recovery mechanism. This affects all moneo appliance deployments with vulnerable versions exposed to network access.

💻 Affected Systems

Products:
  • moneo appliance
Versions: All versions prior to patched release
Operating Systems: Appliance-specific OS
Default Config Vulnerable: ⚠️ Yes
Notes: All default configurations are vulnerable if the appliance is network-accessible.

⚠️ 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 compromise of the appliance with administrative control, potential data exfiltration, and use as a pivot point into internal networks.

🟠

Likely Case

Unauthorized administrative access leading to configuration changes, service disruption, and potential credential harvesting.

🟢

If Mitigated

Limited impact if network segmentation and access controls prevent external access to the appliance.

🌐 Internet-Facing: HIGH - Unauthenticated remote exploitation makes internet-facing instances immediately vulnerable to takeover.
🏢 Internal Only: HIGH - Even internally, any network-accessible vulnerable appliance can be compromised without credentials.

🎯 Exploit Status

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

The vulnerability requires no authentication and minimal technical skill to exploit based on the description.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check vendor advisory for specific version

Vendor Advisory: https://cert.vde.com/en/advisories/VDE-2024-028

Restart Required: Yes

Instructions:

1. Review VDE advisory VDE-2024-028. 2. Obtain patched version from vendor. 3. Backup configuration. 4. Apply update following vendor instructions. 5. Restart appliance. 6. Verify admin password functionality.

🔧 Temporary Workarounds

Network Isolation

all

Restrict network access to moneo appliance to only trusted management networks

Use firewall rules to block all external access except from authorized IPs

Admin Password Reset

all

Change admin password to strong, unique credential after verifying no compromise

Log into appliance admin interface and change password via settings

🧯 If You Can't Patch

  • Isolate appliance behind firewall with strict IP whitelisting
  • Implement network monitoring for unauthorized access attempts to appliance

🔍 How to Verify

Check if Vulnerable:

Check appliance version against vendor advisory. If version is pre-patch and appliance is network accessible, assume vulnerable.

Check Version:

Check via appliance web interface or vendor-specific CLI command

Verify Fix Applied:

Verify appliance version matches patched version from vendor advisory and test password recovery functionality.

📡 Detection & Monitoring

Log Indicators:

  • Unusual password reset attempts
  • Admin login from unexpected IP addresses
  • Configuration changes without authorized user

Network Indicators:

  • HTTP requests to password recovery endpoints from unauthorized sources
  • Unusual traffic patterns to appliance management interface

SIEM Query:

source="moneo_appliance" AND (event_type="password_reset" OR event_type="admin_login")
