DescriptionCVE.org

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.

AnalysisAI

Sudo before 1.9.17p1 contains a local root escalation vulnerability (CVE-2025-32463, CVSS 9.3) through the --chroot option, which loads /etc/nsswitch.conf from the user-controlled chroot directory instead of the host system. KEV-listed with EPSS 26.5% and public PoC, this vulnerability allows any user with sudo --chroot access to achieve root privileges by placing a malicious nsswitch configuration and library in their chroot.

Technical ContextAI

When sudo processes a command with --chroot, it changes the filesystem root before resolving NSS (Name Service Switch) modules. Because /etc/nsswitch.conf and the NSS libraries are loaded from the user-controlled chroot directory, an attacker can place a malicious nsswitch.conf that points to a crafted shared library. Sudo (running as root) loads this library, executing attacker-controlled code with root privileges. The vulnerability requires the user to have sudoers permission to use --chroot, but in environments where this is permitted, it's trivially exploitable.

RemediationAI

Upgrade sudo to 1.9.17p1 or later. If unable to upgrade, remove --chroot permission from sudoers entries. Audit sudoers configuration for --chroot usage. Check for exploitation indicators in sudo logs.
