### User Comments:

### 📊 Metadata *

_Please enter the direct URL for this bounty on huntr.dev. This is compulsory and will help us process your bounty submission quicker._

#### Bounty URL: https://www.huntr.dev/bounties/1-pip-hackingtool

### ⚙️ Description *

The issue consisted in a `arbitrary command injection` which was possible due to the usage of `os.system`, which was used to `execute` commands formatted with `user-supplied` inputs, without any check.

### 💻 Technical Description *

The issue has been fixed using the `subprocess.run()` method, which belongs to a native library (`subprocess`) and is similar to `execFile` in Node. It takes the `name` of the program and then all the `arguments` which contain `user supplied` input and makes sure not to evaluate them as `commands` even if bash characters like `||` or `;` are inserted as `input`, fixing the vulnerability.

### 🐛 Proof of Concept (PoC) *

1. `python3 hackingtool.py`
2. Choose option `01` --> `3`
3. Insert the option `Run` and when a `IP` is requested, insert the following: `evil.com || touch HACKED #` 
4. A file named `HACKED` will be created 

### 🔥 Proof of Fix (PoF) *

Same steps of above with the fixed version

### 👍 User Acceptance Testing (UAT)

`subprocess.run()` has the same functionality of `os.system()` and `real time` outputs are enabled by default, so nothing works wrong :smile:
