UBTU-24-200041 - Ubuntu 24.04 LTS must prevent a user from overriding the disabling of the graphical user interface autorun function.

Information

Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators.

Satisfies: SRG-OS-000114-GPOS-00059, SRG-OS-000378-GPOS-00163, SRG-OS-000480-GPOS-00227

Solution

Configure the Ubuntu 24.04 LTS GNOME desktop to not allow a user to change the setting that disables autorun on removable media.

Add the following line to "/etc/dconf/db/local.d/locks/00-security-settings-lock" to prevent user modification:

/org/gnome/desktop/media-handling/autorun-never

Update the dconf system databases:

$ sudo dconf update
