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
A heap buffer overflow vulnerability in Wibu CodeMeter Runtime network service up to version 7.60b allows an unauthenticated, remote attacker to achieve RCE and gain full access of the host system.

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

A heap buffer overflow vulnerability in the Wibu CodeMeter Runtime network service (versions up to 7.60b) allows an unauthenticated remote attacker to execute arbitrary code and gain full control of the host system due to insufficient bounds checking in the network communication handler.

MitigationUpgrade Wibu CodeMeter Runtime to a version newer than 7.60b; if immediate patching is not feasible, implement network segmentation to restrict unauthorized access to the CodeMeter service port from untrusted networks.

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 if Wibu CodeMeter Runtime is installed
    Check for the presence of CodeMeter Runtime software on the system. This may be listed in installed programs (Windows), package managers (Linux), or running services.
    Affected if CodeMeter Runtime is present on the system.
  2. Determine the installed version of CodeMeter Runtime
    Locate and read the version information of the installed CodeMeter Runtime. Compare the version number against the affected range: versions less than 7.60c are vulnerable.
    Affected if The installed version is lower than 7.60c (for example, 7.60b or earlier).
  3. Verify if the CodeMeter network service is running
    Check if the CodeMeter Runtime network service (Cm Wan Server or similar network service component) is actively running and listening on network ports.
    Affected if The network service component is running and accepting connections.
  4. Assess network exposure of the CodeMeter service
    Determine whether the CodeMeter network service port is exposed to untrusted networks or accessible from outside the local host.
    Affected if The service is reachable from network segments that contain untrusted or unknown users, making remote exploitation possible.

A system is affected if it runs Wibu CodeMeter Runtime version lower than 7.60c (or any of the listed Trumpf products within their affected version ranges) with the network service enabled and accessible to untrusted network access.

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.

dbcve · scoped
Upgrade available Upgrade to 7.60c or later
Fixed in 7.60c
Interim mitigation

Upgrade Wibu CodeMeter Runtime to a version newer than 7.60b; if immediate patching is not feasible, implement network segmentation to restrict unauthorized access to the CodeMeter service port from untrusted networks.

Recommended fix High confidence

CodeMeter Runtime 7.60c or later

  1. Upgrade CodeMeter Runtime to version 7.60c or later
  2. For products bundled with CodeMeter Runtime (Oseon, Programmingtube, Teczonebend, Tops Unfold, Topscalculation, Trumpflicenseexpert, Trutops), ensure the underlying CodeMeter Runtime component is updated to 7.60c or newer
  3. Verify the installed version matches or exceeds the fixed release
  4. Restart CodeMeter Runtime service after upgrade to ensure changes take effect
