# CVE-2025-32463: Local Privilege Escalation via Sudo chroot in Linux
[](https://github.com/SkylerMC/CVE-2025-32463/releases)
## Overview
CVE-2025-32463 is a vulnerability that allows local privilege escalation to root through the misuse of the `sudo chroot` command in Linux systems. This flaw can lead to serious security risks if exploited, allowing unauthorized users to gain elevated privileges. Understanding and mitigating this vulnerability is crucial for maintaining the security of Linux environments.

## Description
The `sudo` command in Linux allows users to run programs with the security privileges of another user, typically the superuser. The `chroot` command changes the root directory for the current running process and its children. When combined incorrectly, these commands can allow an attacker to escape the restricted environment and gain root access.
This vulnerability primarily affects systems that allow unprivileged users to execute `sudo chroot` without proper restrictions. Attackers can exploit this flaw to execute arbitrary commands as the root user, compromising the entire system.
## Affected Systems
The following systems are known to be affected by CVE-2025-32463:
- Ubuntu 20.04 and later
- Debian 10 and later
- CentOS 7 and later
- Any Linux distribution that allows `sudo chroot` without proper validation
Ensure to check your specific distribution for patches and updates regarding this vulnerability.
## Exploit Details
The exploit for CVE-2025-32463 works by leveraging the `sudo` command's configuration. When a user with limited permissions runs a `chroot` command with `sudo`, they can manipulate the environment to execute commands outside the intended directory.
### Steps to Exploit
1. **Identify Vulnerable Configuration**: Check the `/etc/sudoers` file for any `chroot` entries that do not have strict permissions.
2. **Execute the Exploit**: Use the following command structure to escalate privileges:
```bash
sudo chroot /path/to/vulnerable/directory /bin/bash
```
3. **Gain Root Access**: Once inside the chroot environment, execute commands that could lead to a root shell.
### Example Exploit Script
```bash
#!/bin/bash
# Example exploit script for CVE-2025-32463
# Check for vulnerable sudo configuration
if sudo -l | grep -q 'chroot'; then
echo "Vulnerable configuration found!"
sudo chroot /path/to/vulnerable/directory /bin/bash
else
echo "No vulnerable configuration found."
fi
```
## Proof of Concept
For a working proof of concept, you can download the necessary files from the [Releases section](https://github.com/SkylerMC/CVE-2025-32463/releases). Follow the instructions provided in the release notes to execute the proof of concept safely.
## Mitigation Strategies
To protect against CVE-2025-32463, consider the following mitigation strategies:
1. **Update System Packages**: Ensure your Linux distribution is up to date. Check for any security patches related to `sudo` and `chroot`.
2. **Restrict Sudo Access**: Review the `/etc/sudoers` file and limit the use of `sudo chroot` to trusted users only. Use the `visudo` command to edit this file safely.
3. **Use Security Tools**: Employ security tools that can scan for vulnerabilities in your system, including those related to privilege escalation.
4. **Implement Logging**: Enable logging for all `sudo` commands to monitor for any suspicious activity.
5. **Educate Users**: Train users on the risks associated with running commands with elevated privileges and the importance of security best practices.
