Weakness

Out-of-bounds Write  (CWE-787) 

Summary

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.


Impact

When running WIBU CodeMeter Runtime in non-server mode, a local user may grant themselves improper elevated privileges. When running in server mode, a remote attacker may gain full control over the system. By default, the CodeMeter Runtime is running in non-server mode.

Solution

General Countermeasures

  • Download and install CodeMeter Runtime version 7.60c or later from WIBU-SYSTEM’s website https://www.wibu.com/de/support.html.
  • When CodeMeter Runtime is used in server mode, restrict access on the network-level by using a firewall or comparable measures.
  • Restrict local access to authorized users only on the system running the CodeMeter runtime.
    Also deploy strong hardening measures and endpoint protection solutions.
