Vulnerability from github – Published: 2026-03-23 03:31 – Updated: 2026-03-23 03:31

Details

GV Edge Recording Manager (ERM) v2.3.1 improperly runs application components with SYSTEM-level privileges, allowing any local user to gain full control of the operating system.

During installation, ERM creates a Windows service that runs under the LocalSystem account.

When the ERM application is launched, related processes are spawned under SYSTEM privileges rather than the security context of the logged-in user.

Functions such as 'Import Data' open a Windows file dialog operating with SYSTEM permissions, enabling modification or deletion of protected system files and directories.

Any ERM function invoking Windows file open/save dialogs exposes the same risk.

This vulnerability allows local privilege escalation and may result in full system compromise.

Severity

10.0 (Critical)
