However some of these options opens a terminal to perform a specific activity, This terminal is unrestricted and user can access the underlying OS as a ROOT and can run any command on OS.

Underlying OS can be accessed using two methods; Also CVEs are assigned to these findings.

1. Using Ping menu (CVE-2024-41308): it will open a terminal and user can click on File menu -> New Tab/New window. And root level terminal will be open.

2. Using Hardware info (CVE-2024-41309): Once the Hardware info page opens click on Help menu and either select "Open HardInfo Website" or "Report bug", it will open an unrestricted terminal where user can click on File menu -> New Tab/New window. And root level terminal will be open.

Since there is no browser installed in the OS these option by default opens the terminal using it we can access the restricted terminal.


Click on Hardware info it will popup the info software. Click on Hardinfo website or Report bug.
