Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Ilevia EVE X1 Server firmware versions ≤ 4.7.18.0.eden contain an execution with unnecessary privileges vulnerability in sync_project.sh that allows an attacker to escalate privileges to root. Ilevia has declined to service this vulnerability, and recommends that customers not expose port 8080 to the internet.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Ilevia EVE X1 Server firmware contains a script (sync_project.sh) that executes with elevated privileges beyond what is necessary for its function. This allows a local attacker to escalate privileges from their current user level to root, achieving full system control. The vulnerability affects firmware versions 4.7.18.0 and below.

MitigationSince the vendor has declined to provide a patch, organizations should immediately restrict network access to port 8080, implement network segmentation to prevent unauthorized local access, and consider compensating controls such as application whitelisting or monitoring for suspicious script execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify firmware version
    Access the device administrative interface or check system information to retrieve the installed firmware version. This is typically found in Settings > System > About or similar menu path.
    Affected if The firmware version is 4.7.18.0 or lower
  2. Locate the sync_project.sh script
    Search for the sync_project.sh file on the filesystem. Common paths may include /usr/local/bin/, /opt/, or /scripts/. Use the command: find / -name sync_project.sh 2>/dev/null
    Affected if The script exists on the system and runs with elevated privileges
  3. Check script file permissions and ownership
    Run ls -la on the sync_project.sh file to examine ownership (whether it is owned by root) and permissions (especially if it has the setuid bit or runs with sudo).
    Affected if The script is owned by root and has elevated execution permissions
  4. Verify if the script executes as root
    Inspect the script contents or observe its execution context to determine if it runs commands as the root user or with sudo privileges.
    Affected if The script executes with root-level privileges without proper constraint
  5. Check network exposure of port 8080
    Use netstat or ss to check if port 8080 is listening and exposed: netstat -tuln | grep 8080 or ss -tuln | grep 8080. Also verify firewall rules.
    Affected if Port 8080 is externally accessible, enabling remote authenticated attackers to reach the vulnerable script

You are affected if your firmware version is 4.7.18.0 or below AND the sync_project.sh script exists with elevated privileges and is accessible via port 8080 or locally.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to a release after 4.7.18.0
Interim mitigation

Since the vendor has declined to provide a patch, organizations should immediately restrict network access to port 8080, implement network segmentation to prevent unauthorized local access, and consider compensating controls such as application whitelisting or monitoring for suspicious script execution.

Recommended fix High confidence
  1. Review all network firewall rules and configurations for systems running Eve X1 Server Firmware
  2. Identify any exposure of port 8080 to untrusted/external networks
  3. Configure firewall rules to block inbound traffic on port 8080 from external/untrusted sources
  4. If remote administrative access to port 8080 is required, implement VPN connectivity or restrict access to trusted IP addresses only
  5. Verify that port 8080 is no longer directly accessible from the internet
  6. Document and monitor any attempts to access port 8080 from external addresses
