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
Entrust nShield Connect XC, nShield 5c, and nShield HSMi through 13.6.11, or 13.7, might allow a physically proximate attacker to gain access to the EOL legacy bootloader.

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.

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.

Fixed in 13.6.1213.9.0
Recommended fix High confidence

Firmware version 13.9.0 or later for all affected nShield product lines (5c, HSMi, Connect XC)

  1. 1. Identify the specific nShield product model (5c, HSMi, or Connect XC Base/Mid/High) currently deployed
  2. 2. Determine the current firmware version by accessing the unit's management interface or using the nShield CLI tools
  3. 3. Download the firmware version 13.9.0 or later from Entrust's official support portal at www.entrust.com or via the nShield software distribution
  4. 4. Follow Entrust's documented firmware update procedure for the specific product model, which typically requires physical access to the HSM device
  5. 5. Verify the firmware update was successful by confirming the new version in the management interface
  6. 6. Ensure the device is physically secured to mitigate the physical proximity requirement of this vulnerability
Caveat Firmware updates on HSM devices may require re-initialization or re-configuration; verify all critical security parameters and key material are properly backed up before upgrading
