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
Use after free vulnerability in Softing smartLink HW-DP or smartLink HW-PN webserver allows HTTP DoS. This issue affects: smartLink HW-DP: through 1.31 smartLink HW-PN: before 1.02.

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

Use-after-free vulnerability in the webserver component of Softing smartLink HW-DP (through v1.31) and smartLink HW-PN (before v1.02) industrial gateways allows remote attackers to cause HTTP denial of service via specially crafted HTTP requests.

MitigationUpdate firmware to vendor-supplied patched versions for both smartLink HW-DP and smartLink HW-PN devices; if no patch available, consider network segmentation to limit webserver exposure.

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 the device model
    Access the device web interface, CLI, or management console and confirm the exact model is either smartLink HW-DP or smartLink HW-PN industrial gateway
    Affected if Device is a Softing smartLink HW-DP or smartLink HW-PN gateway
  2. Retrieve the installed firmware version
    Locate the firmware version information in the device web interface system status page, or via CLI command (consult device documentation for exact command)
    Affected if Unable to determine the firmware version from the device
  3. Check smartLink HW-DP version
    For smartLink HW-DP devices, compare your installed firmware version against the affected range: any version through v1.31
    Affected if smartLink HW-DP with firmware v1.31 or any earlier version
  4. Check smartLink HW-PN version
    For smartLink HW-PN devices, compare your installed firmware version against the affected range: versions before v1.02
    Affected if smartLink HW-PN with firmware version v1.01, v1.00, or earlier
  5. Verify webserver is exposed
    Confirm the webserver component is accessible on the device (typically ports 80 or 443) and not disabled or restricted via access controls
    Affected if Webserver is accessible and device firmware is in an affected version range

Device is affected if it is a Softing smartLink HW-DP with firmware v1.31 or earlier, or smartLink HW-PN with firmware before v1.02, and the webserver component is accessible on the network.

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.
