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
The Meinberg SyncBox/PTP/PTPv2 devices have default SSH keys which allow attackers to get root access to the devices. All firmware versions up to v5.34o, v5.34s, v5.32* or 5.34g are affected. The private key is also used in an internal interface of another Meinberg Device and can be extracted from a firmware update of this device. An update to fix the vulnerability was published by the vendor.

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 · moderate confidence

Meinberg SyncBox/PTP/PTPv2 devices contain hardcoded/default SSH private keys that allow remote attackers to gain root access. The private key can be extracted from firmware updates of related Meinberg devices, enabling unauthenticated remote compromise of affected devices.

MitigationUpdate firmware to the patched version (v5.34o, v5.34s, v5.32*, or 5.34g or later) per vendor guidance. If immediate patching is not feasible, disable or restrict SSH access through network controls.

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 device model
    Access the device management interface or use network discovery to confirm the device is a Meinberg SyncBox, PTP, or PTPv2 device. Check the device's web interface, console, or SNMP information for the model designation.
    Affected if The device is a Meinberg SyncBox, PTP, or PTPv2 model.
  2. Check firmware version
    Log into the device management interface or use the CLI (SSH or console) to retrieve the firmware version. Navigate to the system status or firmware information section. Compare your installed version against the affected ranges: < 5.34o, < 5.34s, < 5.32, < 5.34g.
    Affected if The installed firmware version is lower than 5.34o, 5.34s, 5.32, or 5.34g.
  3. Verify SSH access status
    Confirm whether SSH is enabled and accessible on the device. Check the device configuration settings for SSH service status. Attempt a connection to port 22 (or the configured SSH port) from a management network.
    Affected if SSH is enabled and reachable on the network.
  4. Inspect SSH key configuration
    If you have administrative access to the device, examine the SSH server configuration and installed authorized_keys. Look for any default, manufacturer-embedded, or static SSH private keys in the device firmware or configuration.
    Affected if Default or hardcoded SSH keys are present in the device configuration.

The environment is affected if it contains a Meinberg SyncBox/PTP/PTPv2 device running firmware version below 5.34o/5.34s/5.32/5.34g with SSH access enabled.
