SYSTEM code execution via unquoted updater path
Published Jun 19, 2026 · Updated Jun 19, 2026
Privilege escalation in Comodo Chromodo Browser 52.15.25.664 allows local users to execute code as SYSTEM through its updater service. The ChromodoUpdater service registers an executable path containing spaces without enclosing the full path in quotation marks, so Windows can resolve an attacker-placed executable earlier in the path. Low-privileged local access plus write permission to a searched parent directory is required, and execution occurs when the service restarts or Windows reboots.
