描述
A proof-of-concept for the CVE-2021-25646, which allows for Command Injection
介绍
# CVE-2021-25646 Proof-of-Concept (Go Version)
## Overview
This repository contains a proof-of-concept (PoC) exploit for [CVE-2021-25646](https://nvd.nist.gov/vuln/detail/CVE-2021-25646), a critical remote code execution vulnerability in [Apache Druid](https://druid.apache.org/).
The exploit is written in Go and allows for interactive command injection via the terminal.
---
## Features
- **Interactive Command Injection:**
Execute arbitrary commands on a vulnerable Apache Druid server through an interactive shell interface.
---
## Build
You need [Go](https://golang.org/dl/) installed (version 2.23.4 recommended).
```bash
go build .
```
This will produce a binary in the current directory.
---
## Usage
You can run the exploit either by building the binary or directly with `go run`.
### Command-Line Options
- `-i` : Target Druid server IP address (required)
- `-p` : Target Druid server port (required)
- `-proxy` : Specifying the proxy url (optional)
### Examples
**Run the built binary:**
```bash
./cve -i 127.0.0.1 -p 8888
```
**Or run directly with Go:**
```bash
go run main.go -i 127.0.0.1 -p 8888
```
---
## Example Session
```bash
$ ./cve -i 127.0.0.1 -p 8888
~ $ whoami
root
~ $ uname -a
Linux druid-server 4.15.0-123-generic #126-Ubuntu SMP ...
```
---
## Technical Details
- **Vulnerability:**
The exploit abuses improper input validation in the Druid `indexer` component, specifically in the `task` API, allowing for command injection via crafted JSON payloads.

## ToDo
- [ ] Add support for HTTPS
- [ ] Automate switch to reverse shell
- [ ] More native command prompt feeling
