CVE-2025-32463 identifies a critical inclusion of functionality from untrusted control sphere vulnerability in Sudo that enables local users to obtain root access by exploiting premature chroot operations that allow malicious /etc/nsswitch.conf files from user-controlled directories to load arbitrary shared libraries with root privileges during command validation. This vulnerability affects Sudo versions 1.9.14 through 1.9.17, achieving a CVSS score of 9.4 (Critical severity) with EPSS percentile of 2.0 indicating high exploit risk for Linux and Unix systems utilizing Sudo for privilege escalation and administrative access control across enterprise environments, server infrastructure, and multi-user systems. The vulnerability details reveal that inadequate timing of chroot operations in the pivot_root function causes Sudo to change root directory before fully parsing sudoers files and validating user commands, enabling attackers to place malicious nsswitch.conf files that instruct the dynamic linker to load user-controlled shared libraries, creating substantial exploit risk for systems where local users can exploit the --chroot option to bypass standard privilege validation mechanisms and gain unauthorized root access. The root cause analysis reveals that the vulnerability stems from premature chroot execution in the pivot_root function called from set_cmnd_path and command_matches methods where inadequate sequencing of directory changes and sudoers validation enables untrusted configuration file inclusion during privilege evaluation, classified as CWE-829 (Inclusion of Functionality from Untrusted Control Sphere). The vulnerability specifically affects the command validation workflow where early pivot_root invocation allows attackers to exploit known exploited vulnerabilities targeting dynamic library loading mechanisms to execute arbitrary code with root privileges through maliciously crafted nsswitch.conf files that specify user-controlled shared libraries for name service resolution. Mitigation steps require immediate upgrading to Sudo version 1.9.17p1 or later which removes the vulnerable pivot_root function and reverts the problematic chroot timing changes introduced in version 1.9.14, with the chroot feature marked as deprecated and scheduled for complete removal in future releases. Organizations should prioritize identifying systems running vulnerable Sudo versions across all Linux and Unix infrastructure, implement immediate patches for critical production systems, audit system configurations for potential chroot option usage that could be exploited, restrict local user access where possible until patching is completed, monitor for suspicious privilege escalation attempts and unauthorized root access, and maintain updated vulnerability database records to track similar privilege escalation vulnerabilities that could compromise system security through local access attacks and broader security implications for multi-user environments and shared computing infrastructure with insufficient privilege separation controls.
