FKIE_CVE-2026-81573
Vulnerability from fkie_nvd - Published: 2026-08-27 10:16 - Updated: 2026-09-01 20:56
Severity
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.

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.
