Description
If CodeMeter Runtime before 8.41a or 9.10 is configured as a server, the configuration command handler does not enforce network-
origin restrictions. Commands intended only for local or same-network clients can therefore be executed by
arbitrary remote peers. An attacker can read potentially sensitive configuration data and overwrite selected values
in Server.ini. This does include the hash of the credentials for the CodeMeter WebAdmin, enabling WebAdmin
takeover.

AI Analysis

Impact

The CodeMeter Runtime servers lack enforcement of network-origin restrictions for certain configuration commands. As a result, any network client—regardless of location—can send commands that are intended to be restricted to local or same‑network clients. This flaw allows an attacker to read sensitive configuration data and modify entries in Server.ini, including the hash of the CodeMeter WebAdmin credentials, potentially enabling full administrative takeover of the WebAdmin interface.

Affected Systems

The vulnerability affects CodeMeter Runtime from Wibu Systems, specifically versions prior to 8.41a and prior to 9.10. These versions are identified by the CPE strings for wibu-systems-ag:codemeter-runtime across 6.x and 7.x branches.

Risk and Exploitability

The flaw receives a CVSS score of 8.6, indicating high severity. No EPSS score is provided, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. While the description does not list a public exploit, the conditions required are minimal: the target must be running one of the affected runtime versions and be configured as a server. The likely attack vector is over a network, whereby any remote peer can misuse the improper access controls to alter configuration settings.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade CodeMeter Runtime to version 8.41a or newer, or to 9.10 or later, which patch the access control flaw.
  • Restrict the runtime’s network exposure by limiting connections to trusted local or same‑network clients only.
  • Verify the integrity of Server.ini after any configuration change and monitor for unauthorized modifications.
