CVE-2025-34518
📋 TL;DR
CVE-2025-34518 is a relative path traversal vulnerability in Ilevia EVE X1 Server firmware that allows attackers to read arbitrary files on the system. This affects all firmware versions ≤ 4.7.18.0.eden. The vendor has declined to service this vulnerability, leaving customers responsible for mitigation.
💻 Affected Systems
- Ilevia EVE X1 Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive system files, configuration files, password files, or other critical data, potentially leading to full system compromise.
Likely Case
Attackers will read configuration files, logs, and other sensitive data to gather information for further attacks.
If Mitigated
With proper network segmentation and access controls, the impact is limited to internal network access only.
🎯 Exploit Status
Exploitation requires network access to port 8080. The vulnerability is simple to exploit with publicly available details.
🛠️ 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 the internet.
🔧 Temporary Workarounds
Block Internet Access to Port 8080
linuxPrevent external access to the vulnerable service by blocking port 8080 at the network perimeter.
iptables -A INPUT -p tcp --dport 8080 -j DROP
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" port port="8080" protocol="tcp" reject'
Network Segmentation
allIsolate EVE X1 Server to a restricted network segment with limited access.
🧯 If You Can't Patch
- Implement strict network access controls to limit access to port 8080 only to trusted internal systems
- Monitor network traffic to port 8080 for suspicious file access patterns and implement IDS/IPS rules
🔍 How to Verify
Check if Vulnerable:
Check if firmware version is ≤ 4.7.18.0.eden and test access to get_file_content.php with path traversal payloads.Check Version:
Check device web interface or administrative console for firmware version informationVerify Fix Applied:
Verify port 8080 is not accessible from untrusted networks and test path traversal attempts fail.📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns in web server logs
- Multiple requests to get_file_content.php with ../ patterns
Network Indicators:
- External connections to port 8080
- HTTP requests containing path traversal sequences (../)
SIEM Query:
source_port=8080 AND (uri_path="*get_file_content.php*" AND (uri_query="*../*" OR uri_query="*..%2f*"))
