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
Innominate mGuard with firmware before 7.6.6 and 8.x before 8.1.4 allows remote authenticated admins to obtain root privileges by changing a PPP configuration setting.

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 Innominate mGuard firewall appliance allows authenticated administrator users to escalate privileges to root by modifying PPP configuration settings. This is a privilege escalation vulnerability where an admin-level user can gain full system root access through the PPP configuration interface.

MitigationUpdate mGuard firmware to version 7.6.6 or later (for 7.x branch) or 8.1.4 or later (for 8.x branch). If immediate patching is not possible, restrict administrative access to trusted personnel and monitor for unauthorized configuration changes.

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. Confirm mGuard device model
    Access the device management interface or check system information to verify the device is an Innominate mGuard firewall appliance.
    Affected if The device is not an Innominate mGuard product, this CVE does not apply.
  2. Check firmware version
    Navigate to the device admin interface (typically via web UI or CLI) and locate the firmware version information, usually found under System > Status, System > Firmware, or via 'show version' command.
    Affected if Firmware version is <= 7.6.6 OR equals 8.0.0, 8.0.1, 8.0.2, 8.0.3, 8.1.1, 8.1.2, or 8.1.3.
  3. Verify PPP configuration access
    Check if the PPP (Point-to-Point Protocol) configuration module is enabled and accessible within the administrative web interface, typically under Network > PPP or Configuration > Interfaces > PPP.
    Affected if PPP configuration interface is available to administrator-level users.
  4. Audit admin user accounts
    Review the list of users with administrative privileges on the device, typically found under User Management, Administrators, or similar section in the web UI.
    Affected if There are multiple administrator accounts or the account may have been compromised.

If the device is an Innominate mGuard firewall running an affected firmware version (<=7.6.6 or 8.0.x or 8.1.1-8.1.3) AND the PPP configuration interface is accessible to admin users, then the environment is affected by this privilege escalation vulnerability.

dbcve · scoped
Upgrade available Upgrade to a release after 7.6.6
Interim mitigation

Update mGuard firmware to version 7.6.6 or later (for 7.x branch) or 8.1.4 or later (for 8.x branch). If immediate patching is not possible, restrict administrative access to trusted personnel and monitor for unauthorized configuration changes.

Recommended fix High confidence

Upgrade to mGuard firmware 7.6.6 or later for 7.x branch, or 8.1.4 or later for 8.x branch

  1. 1. Identify the current mGuard firmware version by accessing the device's web interface or CLI
  2. 2. If running firmware 7.x version <= 7.6.5, upgrade to firmware 7.6.6 or later
  3. 3. If running firmware 8.x version 8.0.0, 8.0.1, or 8.0.2, upgrade to firmware 8.1.4 or later
  4. 4. Download the appropriate firmware from the vendor's official support portal
  5. 5. Upload the firmware through the mGuard web interface under 'Maintenance' > 'Firmware Update' or via CLI
  6. 6. Verify the upgrade was successful and the new version is confirmed in the system information
Caveat Review vendor release notes for any configuration changes required after upgrade; test in staging environment before production deployment
