CVE-2026-81573 (GCVE-0-2026-81573)

Vulnerability from cvelistv5 – Published: 2026-08-27 07:09 – Updated: 2026-08-27 13:33

Title

Improper Access Control in Local-Only Configuration Commands

Summary

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.

Severity

Summary

Automation Builder, Drive Application Builder, Virtual Drive, Virtual DrivePlus Impacted by multiple vulnerabilities in Wibu CodeMeter

Scope

5 vulnerabilities in this advisory, including CVE-2026-81573.

CVE-2026-81573

If CodeMeter Runtime is configured as a server, the configuration command handler does not enforce networkorigin 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. CodeMeter Runtime is only affected by the vulnerabilities listed below if it is configured as a server. This is not the default. To verify the setting, check the profiling value IsNetworkServer: - IsNetworkServer=1: configured as a server (affected). - IsNetworkServer=0: not configured as a server.

8.6 (High)

Vulnerability from csaf_trumpfsecokg - Published: 2026-09-15 07:00 - Updated: 2026-09-15 07:00

Summary

TRUMPF: Multiple products affected by Wibu CodeMeter vulnerabilities

Scope

5 vulnerabilities in this advisory, including CVE-2026-81573.

CVE-2026-81573

If the Wibu CodeMeter User Runtime is configured as 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.

8.6 (High)


                
                  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L

Fixed: 38 products Known affected: 76 products

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
