CVE-2025-34515

9.8 CRITICAL

📋 TL;DR

CVE-2025-34515 is a privilege escalation vulnerability in Ilevia EVE X1 Server firmware where the sync_project.sh script runs with unnecessary root privileges. Attackers can exploit this to gain full root access on affected systems. All users running EVE X1 Server firmware versions ≤ 4.7.18.0.eden are affected.

💻 Affected Systems

Products:
  • Ilevia EVE X1 Server
Versions: ≤ 4.7.18.0.eden
Operating Systems: Embedded Linux (firmware-based)
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default firmware installation. Port 8080 is typically exposed for management.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with root-level access, allowing installation of persistent backdoors, data theft, and lateral movement to other systems.

🟠

Likely Case

Attackers gain root privileges on the EVE X1 Server, enabling them to modify configurations, access sensitive data, and use the system as a foothold for further attacks.

🟢

If Mitigated

Limited impact if proper network segmentation and access controls prevent attackers from reaching the vulnerable service.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

The vulnerability is in a shell script with unnecessary root privileges, making exploitation straightforward once access is obtained.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: None

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

Restart Required: No

Instructions:

No official patch available. Ilevia has declined to service this vulnerability. Consider alternative mitigation strategies.

🔧 Temporary Workarounds

Remove unnecessary root privileges from sync_project.sh

linux

Modify the sync_project.sh script to run with minimal necessary privileges instead of root.

chmod 755 /path/to/sync_project.sh
chown nonrootuser:nonrootgroup /path/to/sync_project.sh

Disable or remove sync_project.sh

linux

If the sync_project.sh functionality is not required, disable or remove the script entirely.

mv /path/to/sync_project.sh /path/to/sync_project.sh.disabled

🧯 If You Can't Patch

  • Implement strict network access controls to prevent external access to port 8080.
  • Monitor system logs for unauthorized privilege escalation attempts and unusual root activity.

🔍 How to Verify

Check if Vulnerable:

Check firmware version and examine sync_project.sh file permissions and ownership.

Check Version:

cat /etc/version | grep EVE

Verify Fix Applied:

Verify sync_project.sh no longer runs with root privileges and test privilege escalation attempts.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected execution of sync_project.sh
  • Privilege escalation attempts in system logs
  • Unauthorized root access events

Network Indicators:

  • Unusual connections to port 8080
  • Suspicious network traffic from EVE X1 Server

SIEM Query:

source="eve_server" AND (event="privilege_escalation" OR process="sync_project.sh")
