Sudo Inclusion of Functionality from Untrusted Control Sphere Vulnerability
Sudo contains an inclusion of functionality from untrusted control sphere vulnerability. This vulnerability could allow local attacker to leverage sudo’s -R (--chroot) option to run arbitrary commands as root, even if they are not listed in the sudoers file.
A local attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2025-10-20 under CISA BOD 22-01.
This is a Software Vulnerability (CWE-829) (CWE-829) vulnerability in Sudo Sudo. Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option. Exploitation requires local access, low attack complexity, no authentication required, and no user interaction required.
Probably yes if any of these apply:
