CVE-2025-34516

9.8 CRITICAL

📋 TL;DR

Ilevia EVE X1 Server firmware versions up to 4.7.18.0.eden contain hardcoded default credentials that allow unauthenticated remote attackers to gain administrative access. This affects all customers running vulnerable firmware versions. The vendor has declined to provide a patch, leaving systems permanently vulnerable.

💻 Affected Systems

Products:
  • Ilevia EVE X1 Server
Versions: ≤ 4.7.18.0.eden
Operating Systems: Embedded firmware
Default Config Vulnerable: ⚠️ Yes
Notes: All installations with default configuration are vulnerable. The vulnerability exists in the firmware itself.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to steal sensitive data, deploy ransomware, pivot to internal networks, or disrupt critical operations.

🟠

Likely Case

Unauthorized administrative access leading to data exfiltration, configuration changes, or installation of persistent backdoors.

🟢

If Mitigated

Limited impact if proper network segmentation and access controls prevent exploitation attempts.

🌐 Internet-Facing: HIGH - Direct exposure of port 8080 to the internet makes exploitation trivial for any attacker.
🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could still exploit this vulnerability.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires only knowledge of default credentials and access to port 8080. Public references confirm exploitability.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: None

Vendor Advisory: https://www.ilevia.com/

Restart Required: No

Instructions:

No official patch available. Vendor recommends not exposing port 8080 to internet.

🔧 Temporary Workarounds

Block Internet Access to Port 8080

all

Prevent external access to the vulnerable service using firewall rules

iptables -A INPUT -p tcp --dport 8080 -j DROP
netsh advfirewall firewall add rule name="Block EVE X1 Port" dir=in action=block protocol=TCP localport=8080

Change Default Credentials

all

If possible, change administrative credentials to strong, unique passwords

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate EVE X1 Server from internet and untrusted networks
  • Deploy intrusion detection systems to monitor for authentication attempts on port 8080

🔍 How to Verify

Check if Vulnerable:

Check firmware version via web interface or SSH. If version ≤ 4.7.18.0.eden, system is vulnerable.

Check Version:

ssh admin@<server_ip> 'cat /etc/version' or check web interface System Information page

Verify Fix Applied:

No fix available. Verify workarounds by testing that port 8080 is not accessible from untrusted networks.

📡 Detection & Monitoring

Log Indicators:

  • Failed login attempts followed by successful login with default credentials
  • Unusual administrative activity from new IP addresses

Network Indicators:

  • External connections to port 8080
  • Traffic patterns indicating credential brute-forcing

SIEM Query:

source_port=8080 AND (event_type="authentication_success" OR event_type="admin_access")
