FKIE_CVE-2026-22208

Vulnerability from fkie_nvd - Published: 2026-02-17 15:16 - Updated: 2026-02-18 17:52
Severity ?
9.6 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Summary
OpenS100 (the reference implementation S-100 viewer) prior to commit 753cf29 contain a remote code execution vulnerability via an unrestricted Lua interpreter. The Portrayal Engine initializes Lua using luaL_openlibs() without sandboxing or capability restrictions, exposing standard libraries such as 'os' and 'io' to untrusted portrayal catalogues. An attacker can provide a malicious S-100 portrayal catalogue containing Lua scripts that execute arbitrary commands with the privileges of the OpenS100 process when a user imports the catalogue and loads a chart.
