Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions v2rayL version 2.1.3

Description The issue allows local users to achieve root access. This is because the scripts /etc/v2rayL/add.sh and /etc/v2rayL/remove.sh are owned by a low-privileged user but are executed as root via Sudo.

Recommendations For v2rayL version 2.1.3, consider modifying the ownership or permissions of the /etc/v2rayL/add.sh and /etc/v2rayL/remove.sh scripts to prevent low-privileged users from modifying them, or restrict the Sudo execution of these scripts to authorized users only.
