Vulnerability from fkie_nvd - Published: 2026-08-24 14:16 - Updated: 2026-10-14 13:10
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
A local privilege escalation vulnerability exists in the Restricted Access (Kiosk) Mode implementation of Scheidt & Bachmann entervo HMI prior to V2 R5 P0 M5. The vulnerability affects the external PDF viewer functionality used to display the application manual and its interaction with the underlying Windows operating system. An authenticated low-privileged user can escape the kiosk environment by opening the application manual in the external PDF viewer and abusing the print functionality. Successful exploitation allows execution of arbitrary commands outside the kiosk environment with local administrator privileges.
